This notice was published as a flagrant act of unlawful retaliation against late night shows for criticizing the sitting President. I think it's misleading to present it as a legitimate action, even if the Trump regime might attempt to enforce it and courts might uphold that enforcement. As the only non-regime FCC commissioner remaining has pointed out, the FCC specifically did not engage in the actual rulemaking procedure that's normally required to change these rules, because if they had their retaliatory motivation would have been a huge obstacle.
