Trump is once again threatening to revoke broadcast licenses if networks provide negative coverage of his administration? Does he still not understand how broadcast licenses work and who gets them or is he a petty tyrant who doesn't care about the law?

For context, he posted this last night.

News networks like CNN, MSNBC, ABC and NBC DO NOT HAVE broadcast licenses. Local broadcast stations (i.e. affiliates) hold broadcast licenses. There are NO nationwide network broadcast licenses. There is also no FCC authority to compel political speech or make any editorial decisions at news networks.
