This is an important distinction. Claiming someone else's statements are false in fact is not censorship. What it is though is confirmation that Facebook is a publisher which publishes editorial opinions about things. (It's incidental that they claim their opinions are facts, publishers have been doing that since the beginning of time.)

The only real question is why the government exempts this particular corporation from following the usual rules that publishers have to follow.

It's worse - it's poisoning the well, which can be far more effective than outright censorship.

Look over here and watch me wave my hand while I say 'platform' over and over.

It is more of a soft censorship.
