Linux maintainers are unwilling to get rust into the kernel, so some rust folks decided to start writing a new kernel with same ABI. This allows them to make new architectural decisions. An example being their “frame kernel” (something between a monolithic kernel and a microkernel).
If I may say, it’s more legible and the tooling is way better, right off the bat.
I’m absolutely with you on point 5. As for the rest, I will have to admit that I may have said some things plain wrong. I’m just trying to drive the point that it’s not inmoral and people should be happy anyway. Perhaps in 10 years this is the OS we are all using on our desktops, phones, and wearables. It would be a pity that’s not GPL and it has ads, sure (like maybe Android on x-brand flagship mew phone). But we could then have the LineageOS version of this. And I’d be happy. My poiny being, if that happens (it turns out to be the biggest OS), it will be thanks to its license, allowing it to be a thing for both people, and companies.
