The tech stack is almost always decided by someone in leadership that has no developer experience. Or by the consultant company that will chose the most complicated and difficult to maintain stack because then they can invoice more and will win all future contracts. The trick is to hire someone that is not corrupted by money, someone like the author of this post, who cares more for the users then how much he gets paid.

Not in my experience. If they're throwing it to a group of junior devs they're throwing it to a group of junior devs.
