The people calling for this are a handful of backbenchers in state legislatures. This is nothing short of whataboutism trying to pretend as if "both sides" are equally hostile to free speech-- but on campus, it's abundantly clear who the people hostile to free speech (or at least desirous of placing onerous burdens on its exercise) are.
It's not all about trying to force universities to hire conservative professors. It's about conservatives trying to starve schools they don't like of funding. It's been happening in a lot of places.
Well, my understanding is that the reduction state funding for public universities and colleges is something that's been happening for for quite a while, more or less independent of any concern over universities' ideological outlook.
