I'm no Trump alarmist, but the quote itself is pretty bad, depending on what exactly he means:
they and others of the lamestream media will be thoroughly scrutinized for their knowingly dishonest and corrupt coverage of people, things, and events
That said, I have my doubts that he'll actually follow through on this. He made similar claims in 2016, saying he'd "open up the libel laws" and use them to go after the media or something, but nothing ever came of that either.
I don't blame them, because of the writer's strike, but although I love Lower Decks, it's the last Star Trek show I'd want to watch in a theater. Why not throw a live action season premiere into theaters like Angel Studios did with The Chosen?
I'm not opposed to this idea, I'm just not sure what it would accomplish. Even Mark Zuckerberg understood that you would need a host of celebrities to get people on board with Threads. Nostr has Jack Dorsey and Edward Snowden but you don't see tons of people flocking to that platform.
