There's absolutely something wrong. They're not banning people for not adhering to posting rules in a sub, they're literally banning wrongthink, they're often banning political opinions they dislike or don't align with US democrat party hegemony.

They suppress subs or influence mods to suppress them for them.

There's a myriad of ways in which censorship to shape a narrative happens, and that narrative is as true as the narrative a few twitter users can set, if highlighted as "the majority opinion/the people have spoken" by mainstream media.

There's intervention via subterfuge, not an open contract you either adhere or not.
