I suspect that at a certain level, corporations must have accountability similar to nations. Right now corporations don’t need to be democratic, they don’t need to allow any type of “freedom of speech” and indeed have strong incentives/prohibitions against it in the case of no-disparagement clauses.

I think people may need to be allowed a vote in the companies they work for/monopolies that service them, and that freedom-of-speech rules for corporations, employees, and customers is likely to follow that of their host nations — not equally free everywhere, but that no-disparagement clauses would be legal in the UK and illegal in the USA, for example.
