Like most things that Trump never thinks through, or thinks about at all, that he never "what if's" if his executive order was able to do what he wanted and they did loose the "we are just a platform" bullshit then if they were viewed as a publisher they would be MORE restrictive not less and screen Trumps tweets more and possibly even delete his account due to multiple TOS violations
All of which is the opposite of what he supposedly wants
I have always been surprised that some ingenious hacker has not been able to go in a disable the mobile phone account that he uses for all that tweeting, disable it all together or make it "receive only" or give it the ability to only make voice calls no data mode in or out.
I can only imagine just how unglued Trump would get if for like a week he could not access twitter
