"from inside Windows"

That's a problem right there.

This is why Linux doesn't exist on more PCs - this is a problem.

Imagine a plumber talking about how much better his toilet is than everyone else's - bc everyone believes only a plumber can install it (which was truth for most of Linux history and general PC users).

Nobody took it seriously bc they took it as mostly an odd humblebrag for niche Windows haters.

Not when Windows is actively pushing people away. New computers are a tiny market, people stay with their old computers for decades now.
