This seems to miss the plot on so, so many points. Not worth a read if you came to the comment section first.

Doesn't even discuss open-source when a key point its making is "tech is built on the backs of others".

Tech here can refer to many things. Given the context stated in the article (and literally the title) I think it’s clear the author is talking about SV elites which by definition excludes most of the open source community. And no, a tech company releasing open source code doesn’t amount to much in the face of the firehouse of cash they print. But you should just stick your head back in the sand, it’ll feel better.
