HOW?
I mean, CoDzilla was, is, and always will be cancer, but the answer was making martials stronger, not bringing casters down to their level.
As a middlefag raised on the material by oldfags and grognards (I mean "started with Chainmail and thinks everything past AD&D is heresy" grognards here), there have been people who care about pronouns and shit as a sizable minority in the hobby for a long while. Pathfinder's just the biggest name that bothers throwing them a bone, and they love them enough that they've formed a core leg of their player stool for 5+ years now.
If you want to talk about "moving away from the old core audience", Pathfinder did that when they made Pathfinder Unchained: their original core audience was "people who felt viscerally betrayed that D&D changed its ruleset drastically past 3.5e". It earned the nickname "3.75e" for a reason.
You said you weren't familiar with PF, so I just wanted to give you more of an inside baseball perspective.
TL;DR your groups are not the cosmos and the people who care about this sort of thing are a major part of PF's playerbase.
Who cares about Mr. Ivory Tower sucking his own cock? Numenera and The Strange were interesting book ideas that MC autistically tried to gamify, and their system (the "Cypher System) is their worst part. Meanwhile, Invisible Sun is possibly the most indulgent and pretentious thing he's ever put out, and that's saying something. Look up some of his early interviews about it and it sounds like he's talking about a cult. "It isn't a game, it's a lifestyle" and shit like that.
