Your assumption that government power will invariably be (ab)used to oppress messages the people in government do not like is a dynamic of fascism, not a universal truth.
Authorization could be done with permits, or just tacitly by the notability of the artist. And while one can kind of do some handwaving and liken the latter dynamic to some mild corruption, that is still nowhere near the level of motivated corruption under fascism. And at this point comments invoking phrases like "established media" and "global bureaucratic regime" have a general thrust of pushing us away from liberal institutions and towards fascism, so I find those appeals quite disingenuous.
