There are always limits. Every state has minority shareholder rights, even if the barrier to raising a claim is high.

The other, maybe obvious, area where the majority shareholder's authority is with regard to illegal acts. This is grayer than it seems in complex regulatory environments.

The practical approach is to get New York or California state legislatures to pass strict privacy controls. (I will then get a cheap post office box in that state and "move" my account under those restrictions on any platform that has much of my data.)
