I feel like big / old companies thrive on process and are bogged down in bureaucracy.

Sure there is a process to get a library approved, and that abstraction makes you feel better but for the guy who's job it is to approve they are not going to spend an entire day reviewing a lib. The abstraction hides what is essentially a "LGTM" its just that takes a week for someone to check it off their outlook todos.

Maybe your experience is different.
