Twitter is a commercial product, it is a private square to use your analogy. It can be and is bought and sold on the open market. If you don't like it, come on up and put up an offer like Musk did. If you don't have the money, tough luck; nothing to get furious over. If you do have the money but lose to another buyer, touch luck; nothing to get furious over.

Lest we forget, it's not like Twitter before Musk was about free speech either. In fact, it came to light that Twitter was, as previously rumored, manipulating things behind the scenes to promote certain topics of discussion above others. Musk coming in put a stop to a significant portion of that, which some regions like Japan especially appreciate to this day.
