SFC announced today a multi-pronged, comprehensive initiative to deal with Bambu Lab's AGPLv3 copyleft violations, and with software right to repair for 3D printer users generally.
https://sfconservancy.org/news/2026/may/18/bambu-studio-3d-printer-agpl-violation-response/
The initial plan includes forks, reverse engineering, and further investigation. As always, litigation remains a last resort.

Today, after a ton of work, we publish our Recommendations When Using LLM-backed Generative AI Systems for FOSS Contributions, which reflect the extremely difficult dilemmas that these systems pose for FOSS contributors. We're approaching LLM-gen-AI from a variety of perspectives and this is practical assistance to minimize damage caused by using proprietary systems, whether FOSS contributors reject LLM-gen-AI or choose (voluntarily or by employer mandate) to use them.

SFC announces their Recommendations When Using LLM-backed Generative AI Systems for FOSS Contributions. A guide and set of best practices for using LLMs for creation and maintenance of FOSS projects. As we move into a new era of software development, thoughtful and ethical use of LLM tooling is critical for FOSS contributors to consider. This set of recommendations creates a framework for thinking and working with such tooling for the betterment of FOSS at large.

Today we join various other FOSS advocacy groups like @fsfe@mastodon.social @fdroidorg@floss.social @eff@mastodon.social in addressing an open letter to Google about #keepandroidopen We need open ecosystems and the move to "sideload" software has set a bad paradigm for having control over our devices. You can read more about it here:

Today is a good day to finally #GiveUpGitHub!
& now there's YA reason: last week, #GitHub urged the FOSS community to *oppose* important #California legislation that places transparency and consumer rights requirements on deployment of LLM-gen-AI!
GitHub's tactic? Disinformation claiming #FOSS licenses are incompatible with Cal. Bus. & Prof. Code §22757 and California #SB1000 (which seeks to amend §22757).

The FCC effectively banned all new routers from being sold in the U.S. last week. We've analyzed the situation and have some good news for #OpenWrt, and the #OpenWrtOne! We also discuss how security actually works, and what we're doing to make sure that OpenWrt continues to lead on that front. Check it out at https://sfconservancy.org/blog/2026/apr/02/fcc-router-ban/
SFC's policy fellow, @bkuhn@fedi.copyleft.org, just posted a relevant-to-current-events article entitled “Dealing with Incomplete Copyleft Source That Doesn't Correspond”.
With the recent news about Bambu Studio's AGPL violations, this advice on how to handle a protracted period of “incomplete-ccs” from a vendor is very much needed.

@arstechnica@mastodon.social has a great write up about our Vizio case. They interviewed SFC's Director of Compliance Denver Gingerich:
“Personally, I’m excited to see [more] people interested in improving the devices they have, whether that be to extend their support lifetime for 10-plus years… so they can keep getting security updates after the manufacturer stops updating them, add new features like ad-blocking, or diagnose and fix hardware issues that require software changes,”

We've just heard from the court, the #Vizio trial is scheduled for August 10th! You can join us at #FOSSY in Vancouver, BC and then head down the coast to California for the trial.
Thanks for all your support during this process and while we hope it doesn't get rescheduled again, we're ready to work to #DefendTheGPL as always!

One of the fantastic tracks we're hosting at #FOSSY this year is the "Toolchain and Other Developer Tools". If you have used any of the incredible projects hosted at @sourceware@fosstodon.org or myriad other #FOSS compilers, debuggers, or editors then you should think about giving a talk in Vancouver this August!
We want to hear from you whether you are a first time speaker, veteran of the circuit, or someone who isn't even a professional software developer. Software being made by everyone is one of the best things about #FOSS :)
Submit to the CFP by May 22: https://2026.fossy.ca/call-for-proposals/
