I don’t know why you think that I haven’t tried those configurations in your mind. Are those completely undocumented and cannot be found on the internet or something?
Because having so many unsolvable problems would be an extreme edge case (if you had one, it would be much more likely a bug than a basket full of what you are calling unsolvable problems), and there are a lot of bad setting recommendations out there which make it rather difficult to find the right one for your device. It can take quite a bit of experience and quite a bit of persistence - which is again, as I said, not the way it should be. If you are sure you have exhausted your options, please file bug reports.
If you check a thread about GrapheneOS, almost everybody praises it, and many even state that everything works. If you look into it however, a ton of things simply don’t work, and they just don’t care. Heck, even in this thread there are people like that. They just flat out state, that “it works perfectly”, then a few sentence later “x, y, z don’t work”. So, how should I know that 25+ years of Linux knowledge, custom kernel and Linux building, and tinkering are less, than those people who are fine with their free drivers which don’t utilize half of their hardware’s features?
I have about the same amount of experience with Linux, more on the tinkering and sysadmin/full stack side than custom building (although of course I have to use custom kernel module loading etc), and I still learn a lot more from research on a specific new-to-me problem than from my bank of knowledge. When it's new to me and Vantablack opaque as is the Linux way, I ask rather than waste my time.
What grinds my gears on Linux even more than that is that is is fundamentally unsafe [1], and you can only approach mitigating it. And nobody really cares. I use it because it's the least bad of the major 3 OSes, and I do want a community that can help. But I don't pretend to love it unreservedly. Perhaps I should move to a BSD, but the ecosystem keeps me here.
And I understand if you are certain there are bugs that will be ignored based on your past experiences, I too would be poorly motivated. I am not trying to convince you that you don't know what you know you know. But you can understand that my first take when reading a comment on the internet, even on HN, is that there is always more annoying-and-almost-impossible-to-discover config work to do.
