This was for a "practice" position (rather than a purely academic one), which has different standards. The fact is tenure decisions are almost never reversed by the Board of Regents. They're there to rubber stamp the decision of the college. They certainly don't have the expertise to decide who deserves and who doesn't deserve tenure. People nearly always quit their old jobs long before the Board of Regents officially accepts a tenure decision (think of tenured professors who move elsewhere with tenure intact).
I'm surprised how little you care about an egregious violation of academic freedom and free speech (after all, the person is being punished by the government for her speech). How very libertarian of you. FWIW, FIRE at least cares about this:
