Regardless of your stance on this topic, this is a bad example. Regulating what teachers are allowed to tell students in the course of their employment as teachers is not a freedom of speech issue, any more than the owner of a fast food restaurant requiring their employees to upsell is a freedom of speech issue.

Yes, there are higher ideals in play in the first case, but that does not make it a freedom of speech issue, legally or even ethically. Employers can regulate what you say while working for them on their time, and that holds whether the employer is private or public.
