PF2e actually exists because of D&D 5e. 5e is a streamlined and (most people believe) improved version of 3.5, which is exactly what PF1e is under a different label. But to appeal to their rebellious hipster demographic the new PF had to be different and innovative. So you get a bunch of overly complex rules for options and the sake of just being like D&D but still totally not D&D. The result is a decent game that definitely isn't 5e because it intentionally trades off most of the streamlining that makes 5e more approachable for the sake of complexity and options.

Basically it's a bunch of pretentious hipster BS.
