If I had any idea how to short sell, I'd be short-selling the life out of Twitter stock right about now. Banning Katie Hopkin's has just broken the camels back and now a Twexit is trending.
They must have lost over 500,000 real followers in the last 24 hours and more are following. It just goes to show that you don't need legislation to end commercial censorship, it can be done by people expressing their own free will.
Parler is a lot more peaceful, less angry people, less vicious people. Nobody threatening or calling for others to be banned. I'd recommend to anyone that has or has struggled to get a decent Twitter handle in the past to head over to Parler.com and get your preferred username early.
I suspect that Twitter won't recover from this. Twitter was already in financial trouble anyway. It would be amazingly ironic if banning Katie Hopkin's is the thing that brought it down.
