Slander and complete suppression of his ability to get his message out on social media or the internet.
This is their template for Trump 2020. They will allow Trump to remain online...but will ruthlessly censor his followers from spreading the message between themselves and to others.
Trump is too big for them to take down. Might as well challenge Richard The Lionheart to single combat as try to win the information war with this one. He lives rent free in their head. If they mess with his Twitter, he’ll find a different way.
