When they distinctly act as a publisher, they are a publisher and fraudulently hiding behind protections of being a platform. Twitter is now attempting to determine what information is untrue from selected sources.
So, not only are they making 'in kind political contributions' to the democrat party by erroneously attacking the President, but they can no longer legally offer their publicly traded company as a platform - because they now control content.
I think Trump is acting now because he is the target and it should go quickly to the Supreme Court.
Took 150 posts to get to the meat of the issue - we're slipping around here. Social media has gone off into publisher territory, filtering content by picking and choosing what stays or goes, even inviting in third parties with political action agendas to do the picking. There were threads about that around FR when those outsiders got brought in - guess people forgot about that. They are also collaborating with individual politicians, political operatives and foreign powers - namely the ChiComs. Social media is up to its eyeballs in ChiCom influence, who are now calling in their markers and flexing that influence. Trump knows this and is moving to get a head start on that battle.
