I'll get heat for this but I don't believe in the David vs. Goliath narrative people have for Linux as some sort of bastion against 'big tech'. It's one of the most used OS/kernels in the world, mostly by big tech and their employees motivate most of its development. It's only because it's open source.

I think if people cared enough about competition they'd invest it into improving things like Qubes OS, Secureblue (a novel hardened Linux distribution) or a jump to newer OSes like making Redox OS more available to people.
