@anthropy@mastodon.derg.nz @mntmn@mastodon.social probably has to do with the fact it's a pretty low-volume operation; you can't build a laptop rubber dome keyboard from off-the-shelf components like you can a mechanical keyboard, and cnc machining is much more accessible than injection moulding
you need relatively big economies of scale to build a laptop with those at a price that makes sense (or you could use a keyboard made for another laptop and idk do group buys to get injection moulded plastic shells made? most decently built laptops have a metal roll cage inside anyway so you might as well just make the whole thing out of metal and save yourself the faff)
