Otherwise on topic, I see and feel the chilling effects on speech from those big platforms being discussed across America as well. I do not see any of it coming from the US government, though. I see it all coming from citizens wishing to control others' speech all around them, else they will whip out a phone and think they're some sort of vigilante over others' speech or wrongthink. This is tiresome and old already but I'm not comparing this to government level, authoritarian free speech removal. Still, it's having a mass effect on societal attitude, conversation, politeness, and all else, as far as I can tell.
