The problem is that rules need to be viewpoint neutral to be fair and effective. If we allow authority to pick approved opinions, we end up with this incoherent bullshit. One year you can't mention anything contrary to the CDC and the next you're not allowed to talk about Palestine, only because the dominant political parties switched places. If you tolerate this kind of rule making because you believe your opinions are correct, be ready to be oppressed when the next administration decides they hate you.
