Major fear is corruption of the culture. There are corpos and cunts that would benefit from Steam stopping linux suppory which is a major adoption driver. Nvidia is supposedly a more difficult gpu/cpu to use with linux and the current duopoly leans heavily in their favour.

Impossible. The cloud will fall. And locking the bootloader of computers won't work.

Not illegal, rather not free. There is an ongoing effort to switch from GPL licencing to more restrictive licensing, allowing corpos to close the source of their distribution. Redhat-IBM is at work. All this camouflaged behind good intentions like rewriting GNU user land and libs in Rust because memory safety.
