To the people constantly saying that twitter is a private company and should be allowed to do whatever they want: Would you support the same idea around electrical power? If the power company providing the power to the office at the NyPost decided that they had a political disagreement with them, would it be okay to just cut off their power? NyPost could just make their own power, of course, by purchasing a generator…
With Twitter et al, their service is free and "you are the product", so.. they can ban you whenever with no recourse at all.
