Nope! That was well within Twitter’s legal right.
The First Amendment limits government control not businesses.
So it limits Trump from using a business to disenfranchise people but a business can remove any individual that breaches their contract just as Trump did.
If Twitter was an official government source, and not a private business, then there would be merit to your argument. And I understand the lobbying control power of big businesses and such but you don’t limit that control through dictating what a single business can and can’t do. A government can legislate that, sure but then you get into expanding government control rather than cultivating a free market. What should be limited is lobbying power of businesses, not individual businesses themselves.
But conveniently, many are arguing what YouTube and Twitter should’ve done rather than what Trump and Biden should’ve done. If you want government accountability, then focus your ire on individuals in the government and all of them are subject to criticism. No one is exempt! Including Trump.
All politicians, including Trump, profit off of the manipulation of businesses to sell a product; themselves... for whatever office they hold or wish to hold. You can even make this about career politicians versus whatever the opposite of that which honestly, I think, doesn’t really exist.
All politicians see their position as a way to make money. It is vital for them to campaign! I honestly think there is nothing inherently wrong with that. There is no way to stop this process because NO POLITICIAN, even Trump, or people who want to follow his example will do nothing to stop politicians from raising money. They can’t! And why would they want to? Nor will any form “cancel culture” ultimately succeed in the breaking down of a capitalist-democracy.
Businesses will rise and fall eventually until the product they sell is irrelevant. And even if the most influential businesses in social media is ultimately replaced with new businesses; the people and systems that created and limited what they are now will continue to influence the new businesses that rises in their place.
If you want to fix the echo chamber, then you can’t fix the problems of an echo chamber by making a new echo chamber. Until people realize that social media is useless, unlikely due to its addictive nature, then it shall continue to pedal it’s influence unrelenting no matter what political spectrum you fall under.
