After the election
The purpose of the censorship is to affect the election.
This is the Dems last gasp to end Trump, and end persecution of the elites, and to end the attempt to expose Obama and Hillary and their crimes.
The heads of social media are raging leftists and they have reported for duty to the Left, enlisted in the cause.
I think Trump may do some regulatory actions now, followed by legislation in the future.
The sooner the better.
