I completely agree with Kara Swisher:

That is why Twitter and Facebook and YouTube, which are the three main conduits of online communications for most Americans, must now de-platform Trump permanently.

I do not call for this lightly and have always thought that he should get a wider berth owing to being the most newsworthy person on the planet. But it’s long past time to make an example of him as a persistent violator of platform rules who cynically games their laudable impulse toward allowing as much speech as possible. […]

Twitter — Trump’s favored online communications vehicle — says as much in its civic integrity policy, noting that “you may not use Twitter’s services for the purpose of manipulating or interfering in elections or other civic processes.” Well, he has done that over and over on social media, raging like the monster that he has always been.

Considering the traffic that Trump drives to these services and by definition profits, I am not holding my breath that they will do the right thing.
