It seems like it's difficult to really separate them these days.
You can always come up with something horrific enough that it seems reasonable, even necessary, for platforms to block it, like actual terrorism or child porn.
But then, there's always an activist group out there who really wants to ban something that most people feel is only mildly distasteful but not worth a platform-level ban and will abuse processes to do it.
And there's enough people for each of those cases who have incentive to obscure exactly which category things are actually in. More than enough for it to be hard for any platform to sort it out for sure.
So do we eventually end up with either an actual Government takeover, or everything banned that's more edgy than Mr. Rogers Neighborhood?
