Well, one is a GPU like this one that only has 2D support and it’s apparently perpetually stuck as experimental. The second one is a trackpad / numpad combo that someone else got working but because the code never got upstreamed it broke. The last one is an internal microphone that might have support in the kernel but it might be missing quirk flags or a small change in how it works.

I admire people like this because even though there’s like 3 pieces of hardware I wish I could fix like this, I’ve got no clue where to start. And except for one, most are simpler devices than the M1 GPU.

It’s hard to feel sorry for these non profits even if it the data loss is a tragedy. It’s been years of people screaming that this kind of shit could happen. That not accepting the pain of early adoption of open source software would lead to the extreme pain of being locked out arbitrarily.
