> Requiring that posts stay on topic isn't censorship.

Censorship is exactly what it is. I understand it's an emotionally or ethically charged term for some, but there is no doubt about what they're doing:

"to examine in order to suppress or delete anything considered objectionable"

We all understand that there are terms of service. They're enforcing them via censorship. Whether it's the censorship or the ToS that the censorship is meant to serve which are particularly objectionable is a pretty uninteresting argument.
