laughs nervously in American

I’m no legal expert. Can anyone chime in and tell me if what he’s alleging is even illegal? Seems like he’s saying a bunch of advertisers got together and collectively agreed to not do business with Twitter anymore, ostensibly for a variety of reasons, but mainly because he lied about how their advertisements would never appear near hate speech.

That, to me, feels like something they should be well within their rights to do. A business can’t just force other businesses to do business with them unless they’re like under contract or something. But this doesn’t seem to be a contract dispute unless I’m missing something.
