The argument isn't that they're free from corruption and ideology, but that they're the only real check the public has against powerful monopolies and duopolies

The argument isn't that they're free from corruption and ideology, but that they're the only real check the public has against powerful monopolies and duopolies, etc. At a certain scale, competition breaks down and entrenched enshittification happens.* An average person has some (tiny) input in a representative democracy, where it's one person one vote (even if several layers removed, and only appointed by proxy etc.). They have no real say in a corporation that's usually one dollar one vote. * Yeah, it happens to governments too!
