It is difficult and good programmers deserve high compensation, but there is a reason that there is the trope of the fresh out-of-bootcamp developer working 3 hours a week and making $600k a year

I assume some of them are doing ad sales, which is revenue generating. Probably a lot of HR (which 80%+ of those positions are a grift, IMO), and a lot of other make-work positions. Their product team is like 200 people and they don’t even have any accessibility engineers.
