The mechanisms for outing and booting out this guy works just as well against people you support, like union organizers or whistleblowers or even simply those whose politics doesn't line up with the interests of the business. Union organizers and whistleblowers have specific legal protections because they are deemed not to be engaged in political activities but in legal activities (like organizing a union or revealing fraud or criminal activity). Businesses are otherwise mostly free to terminate workers over their political beliefs unless the business operates in a state which includes political affiliation as a protected class (like California, but notably not New York or New Jersey).
