This is a fairly comprehensive debunking of Trump's tantrum about twitter:

"Legal experts are dubious that Trump can do much to bring the internet companies to heel without legislative action, which is unlikely.
"“If I’m reading this correctly, the EO claims tech platforms are doing something they’re not, in violation of an incorrect interpretation of law, and tasks agencies it can’t task to look into the things that aren’t being done that wouldn’t be wrong,” the legal scholar Tiffany C. Li tweeted."
I do hope Twitter have now reached their sticking point.
