Lol, like you audit the thousands of lines of code when you compile from source.

What made you think they'd be willing to compile from untrusted sources?

There are a lot of users that prefer the established trust model of a Linux distribution. They're willing to trust the mostly unpaid debian maintainers for example... but not John Doe, the temporarily set back billionaire who's just about to make it big

Yes, I look at code. I'm professional developer. I will spend 1-2 minutes at scanning per thousand of lines.

I’m a developer too. Currently job title “senior enterprise systems engineer”. It would take me much longer than that to ensure the code is ok. Additionally without modelling the code (and proving it correct) in something like COQ, you will never understand the calculus of inductive constructions behind the code and have no guarantees as to its correctness.
