So, you don't have a problem with, say, a guy like Trump calling up Jack Dorsey and telling him that he (Trump) will use his powers of office to do XYZ unless Twitter bans anything on ABC topic, and such action by Twitter will give political cover for Trump, which will end up screwing you in the end. Then, worried about such action by Trump, Dorsey does as commanded.
If you have any proof that such a thing is going on, sure, I'd have a problem with it. But good grief, you could make such a claim any time a business does something you don't like. That doesn't make it a valid claim.
I really can't get past the rather obvious observation that this is just sore-loser-ism. You all are pissed off because FB and Twitter banned your troll-in-chief, and you're looking for ANY excuse you can find to get revenge on them. Why can't you just accept the fact that lots of people, lots of businesses, think Trump is bad for the country and they won't support him for that reason?
