They were already starting to pull back from the worst of the cancelly stuff starting a few years ago. It only took a few years before they realized that a lot of it was blatantly self-contradictory (e.g. broad representation in media is impossible if people are only "allowed" to tell "their own" stories). And they might also have gotten the hint that they were scoring a lot of own goals.
A lot of the other stuff, like actual policy, they're still pretty dug into. But IMO there's a greater proportion of that stuff on which they're just correct, so that's kinda respectable for me.
Likewise, I think a lot of the problematic stuff came from legitimately good ideas. They were just co-opted by bad actors, so to speak.
