Imagine if the Biden or Obama Administrations had just openly and blatantly threatened Liberty, Hillsdale, Regent, and Bob Jones Universities on social media and in PR releases with their destruction if they didn't agree to every single demand to placed on them by Biden or Obama or people in their administrations, and they had the federal government go after the very sources of their financial ability to operate and stay open and independent of direct federal control. Conservatives and Fox News and other right-wing media would be screaming bloody murder from the rooftops and calling such a move tyranny, an illegal and radical exertion of federal dominance over private institutions, and all sorts of things.
And yet most Trumpers are gleefully in favor of Harvard being humbled and perhaps destroyed - including Republicans who actually attended the university and are alumni. Insane, and as you pointed out it's going to lead to a decline of American prestige and dominance in science, technology, and other fields, yet here we are. And all because Trumpers are pissed and resentful that most universities are liberal and that people with college degrees have generally fared well in this global economy while many of them haven't.
