In France, a private utility business becoming a monopoly is nationalized, meaning the state takes over. The rationale is that if everyone uses the service, then they are at the mercy of the service provider. It was the case for electricity, natural gas, phone lines and the postal system.

Social media require all users use the same one to connect together. It doesn't make sense for them to compete against each other and segregate users. They are by definition monopolies. By definition this leaves the users at the mercy of social media.

The various social media platforms have been shown to be colluding, or at least acting in a standalone complex: they want to control the narrative, and their narrative is globalism. And foreign countries don't want foreign interference.
