They have not changed. They still maintain this "enlightened centrist" persona, while claiming "both sides are the same". And their social commentary, if you could call it that, is very tame. They did briefly lean into making politicians out to be evil, but they kind of walked that back and now their story lines read more goofy than anything.
The whole premise of the new season is telling. It's not about the suffering people have gone through due to wars (trade or military) or the food situation (the diarrhea parasite / cancer beef ep writes itself). Nope, it's about how the silly goose in office is renaming stuff.
It's possible to be serious and funny, but the new stuff I've seen has been unserious and unfunny.

How is that not changing?
If they are centrist and treating both sides the same, what are your favorite Joe Biden jokes from South Park? Given the number of Trump jokes and the both sidesism you mentioned there should be a lot of material to work with
