Regardless of whether the physical placement was authorized or not, my comment still applies regarding the specific content of the message.
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.
