Censorship, beyond what’s required by law, is doomed to fail.
The article says they were "pressured", it doesn't seem to to say how that pressure was applied. To me, it reads as though compliance was not mandated, just requested. Without more info, I suppose it could be taken either way.
The Biden Harris government is guilty of censorship via a third party.
He isn't suing, and it's up to the rest of us to make our decisions based on how we feel about that.
