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.
I guess I’m a young woman now, if we go by the art of Metal Bringer. 
Did they include AI slop, dogshit mobile game ports, low effort games, and the like in the dataset? If so, I’m not surprised.
The more I think about it the less I see them as victims, and more as irresponsible with important data.
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.
Right wing newspapers love to do this shit where I live. We get into a crisis, people start skipping meals because they don’t have money, and they will talk about the health benefits of dieting and fasting 🙄
