> Nor does he have any real regulatory authority that could be employed that wouldn't also bite him back
I'm not convinced of that. Trump has repeatedly shown he is willing to exercise executive authority to the fullest extent possible and the courts have repeatedly affirmed his ability to do so. I'm not sure what kind of "bite back" you expect, but that kind of thing has never been an obstacle for Trump. At the end of the day I think you're right that he's bullying them, but I think it's wrong to believe that he won't actually go after them if they do not comply with his demands or at the very least retract the fact-check and praise him
