People here have little idea about how Harvard works. Harvard is financially vulnerable. It is currently running on a deficiency considering the endowment. And Harvard can't freely use most endowment for personnels anyway. If the government takes away funding, Harvard will have a financial crisis. I guess the leadership made the decision in hope someone could stop the government before bad things happen but when bad things do happen, you will probably see mass layoffs of researchers in particular in life sciences and biomedical research.
