I find it fascinating the President of the United States is ranting about 1st Amendment violations with regards to a private business. Pretty sure there is nothing in the 1st Amendment that says he is guaranteed the right to tweet.
I hope Twitter takes this a step further the next time he violates their ToS and gives his account a 48 hour suspension.
I understand why Trump is picking this fight but I can't help but feel Twitter hold the power. Sure Trump has been a big driving factor in Twitter really hitting mainstream but I would be surprised if he was still adding huge value to the platform. If anything banning Trump would be the biggest thing to ever happen to Twitter as he wouldn't let it go.
However I can't see a way for Trump to win such a fight. It could go all the way to the SCOTUS but if they sided against Twitter it would affect literally every big social media platform in the US which I can't see happening.
Zooming all the way out I don't see why Twitter really care about such a fight as there is no way Google and Facebook (to name just two) would let things go against Twitter as it would be devastating to them as well.
