Netflix, no. Disney+, no. HBO, no. Replaced binge show watching with trips to the local library. Huge collection of DVD, Blu-ray movies. Found a few books to read. I had enough.

@EUCommission@ec.social-network.europa.eu is there any plan in motion to stop this monopoly from Google on Android? reCAPTCHA now also requires a Google Certified device status. Soon won't be able to use apps without being locked to Google.

Interesting development. Banking apps, to be allowed on Play Store, they must use Play Integrity. As the majority of Android phone users are Play Certified devices, even if old, this means that engineering of said banking apps are pushed to use Play Store and leave everyone else excluded.

This is where we stand. EU regulatory bodies have to wake up to this. A duopoly is here. Soon, there is no other option.

Well, this is getting traction and an email to #MobilePay team on their app solved the issue and they no longer use bootloader status for gating using their app 🥳🤝💫 I can tap to pay using Mobile Pay in Finland on a deGoogled device running non-rooted LineageOS 23.2.

Slowly but surely, #Microslop dominance in corporate is evaporating. Year of Linux has been almost a meme for years, to completely see YouTubers and governments drop Microslop license slugs. Now fund the #opensource projects. A percentage of the money you would pay to Microslop will be more than what most projects receive. Become sponsors. Get involved in fixing and improving the projects you use.

It's almost a year since I joined HMD, and later to HMD Secure. During this time, because we are working with #deGoogled devices, I came to see very sketchy moves by Google in limiting significantly what you experience with a deGoogled device. #Murena e/OS is a great example of what you can achieve when you say no and go against the stream together. It's great to know we are not alone, on a raft and we paddle against the waves of shenanigans Google pushes towards us. It is defiance, it is persistence, it is giving people an option where privacy matters the most.

@nomad99@techhub.social @artelse@mastodon.social @volla@mastodon.social @jolla@techhub.social in Finland, we do have an API that apps can use to validate one's identity via bank credentials. But if banks move to force Play Integrity, we can't approve the bank login to validate one's identity. Which makes it impossible to login on public services, tax office, health care, etc. We are slowly becoming dependent on a Google Certified device to identify who we are. And that is the problem. #Volla, #Jolla, #Murena #HMD Secure devices would be penalized because we take EU Digital Sovereignty seriously and offer deGoogled devices. @gael@mastodon.social @murena@mastodon.social e/OS is also on the same boat if Play Integrity is the only way that developers use to check device integrity.

@EUCommission@ec.social-network.europa.eu it would help to get an official stance on this matter. Meanwhile, I'll meet with MobilePay and hopefully Volla & Jolla to have a deGoogled NFC payment option in European made devices without Google Services. "Thank you for your messages and input. I have forwarded the issue to the appropriate team with you contact details. They will be in contact with you."

This kills any dream of a Google free device that you can use for any banking activities. Do we really want Google to control every single transaction occuring in Europe?

@paoloredaelli@mastodon.uno we don't know what we don't know 😉 I trust we can elect EU representatives which share the same concerns. It is our responsibility to make sure of that if we want change. There are so many items that require attention, some more pressing than others. And we have the option of not using a smartphone at all 🙈 Banks are making their apps only work on such devices with Play Integrity, and closing bank offices. Soon, you can't check your balance, transfer, etc unless you have a smartphone that is certified (iPhone or Google Certified device). Meanwhile, we can have an open dialog like we are having here, so that people around the world also think about what this actually means for them: no alternatives, no options, a monopoly.

@paoloredaelli@mastodon.uno I'm not sure I follow the reasoning behind EU wanting Play Integrity being a mandatory requirement for non Apple devices. Same way EU forced Apple to open their walled garden. The only nuance thing here is, a Google Certified device means that they are running Google's proprietary blobs. So really, the course of action is, install alternative OS/use alternative OS and instead tell the devs of apps with Play Integrity checks that there are alternatives to check a device is not compromised - because that is what it should be about. Force Google to provide a different verification path that allows alternative ROMs/OS to be seen as safe.

The requirement needs to come to developers, not from developers. I am aware that GrapheneOS also does not like the idea of unified attestation and prefers to use what is already on Android APIs. And that is also another option that can coexist. Right now, it is Play Integrity or nothing. That is what needs to change.

Got it for 25€ second hand 👌 also managed to find a soul selling 3x 8GB DDR4 for 40€ so the machine is rocking 32GB of RAM. Should be plenty to game 🎮

@kallekn@mastodonsweden.se if your device was sold with e/OS, your device is fused to e/OS platform key, which means your bootloader is safely locked and with e/OS :) but for us with devices initially sold with another OS version and manufacturer, which don't update the OS or do security patches, it creates e-waste unless we unlock the bootloader to install an up to date OS, for example e/OS on a Samsung or other brand. #eOS is great!

Google responds to Chrome’s silent Gemini Nano install, stops short of addressing consent

What people need to understand is that there was always some sort of data processing on the browser. That's how profiles, your ad profile, is created and how Google makes profit every day. Its selling you, as profiled, for targeted ads. Google wants to do this profiling on your hardware and your electricity bill, not theirs. Is it private? Never was.

Part of me is happy people are realising what "free" actually means. This is not just Google btw. Sure, maybe Google could have asked people: hey, do you want to have your profile data processing done on your machine or ours? Yes, do it locally. No, you can take it on your data centers. It was never a hey don't collect data about me at all.

This is the tip of the iceberg. Add side data, for example camera footage, face recognition, debit/credit card usage, store bought items, etc and you realise you never had a choice. And now you carry a device on your wrist or pocket, listening, recording, processing. Sleep tight.

@paoloredaelli@mastodon.uno @karhima@graz.social for example, my bank uses a an app that receives OTP codes, biometric authentication. However, without Play Services, you can't use it at all. Meaning I need to use a device with them if I want to use my bank, including website. For now, they are not blocking non Google Certified devices, but if they do, it's impossible to do any bank activities.

@sakura84@lgbtqia.space it's worth raising awareness that there are alternatives to Google Play Integrity, for example Promon Shield from Norway https://promon.io/products/shield-mobile and many others. It definitely does not need to be a device that installs apps from the Play Store, and is GMS certified. F-Droid, Aurora Store work well on a deGoogled device but if the apps themselves don't work unless they detect that Play Store is installed, it means only Android with Google services can be used. No alternatives.

There is more to it than meets the eye. A brand model also needs the spare parts suppliers to still have a production line active so that spare parts can be manufactured. So effectively, this means have plenty surplus of items. Which may never be sold, replaced.

And if it's a battery, they need to be recharged after some time if the device is on a shelf in a warehouse. While the intent is good, this will make things more expensive. Because that is the only way to comply with this regulation.

There is an acute supply of people who can fix electronics. When the price to repair is more than to get a new one, people will pick the cheapest option. And so will manufacturers. This regulation makes the cheapest option expensive, so that repairs seem cheaper, but they will be more expensive than what they could be.

@nomad99@techhub.social @artelse@mastodon.social @volla@mastodon.social @jolla@techhub.social eIDAS is the protocol used in Finland, and it's linked to your social security identifier or phone number (Mobile Certificate) https://dvv.fi/en/identification Banks here use it to verify you are who you say you are. But we never get to this stage as the app will not run if the device integrity check is using Play Integrity. For example, Danske Bank main banking app works, but the Mobile ID app is not installable unless you have a Play Certified device (you won't find it on the Play Store) and you need to get it from alternate stores. Once you have the apk, you can sideload it, and identify and verify your identity with eIDAS. But if Mobile ID enforces Play Integrity as well, means I can't login at all on the main banking app. Or on the web banking for that matter. Basically I'm unable to use any banking services. For now, this is not enforced. But I want to make sure it never is, or that there is room for deGoogled, non Google Certified devices to exist.

@nomad99@techhub.social @artelse@mastodon.social @volla@mastodon.social @jolla@techhub.social thank you for the link. These are two separate discussions. One is about the ability to use devices without Google. Digital Wallet, and Digital IDs piggyback on the trust of the devices they are running on. If we can't verify the device is secure and untampered with, you cannot protect someone's funds (digital wallet) or their identity (digital ID). This is why it is of upmost importance that Play Integrity alternatives exist. Because otherwise, you will not have any choice other than use Google Certified devices.
