Mixed.
There is no way they could have known when they amended their charter from religious to educational that this would have been the outcome but they should have realized that there would be consequences from doing so.
I certainly don’t their amending their charter from religious to educational as worse than a mosod that bends the rules for government funds. Not that all or most mosdos do ch’v but no reason to single out YU in this regard.
As far as the old complaints about YU graduate schools law having toeva groups, Touro law also very clearly gives their affiliation with toeva groups on their website and no one says a word. Realistically speaking there is a limit how much you can fight the supreme rights that liberals have given toeva groups which allows them to marginalize the rights of everyone else. If you vote for pro toeva candidates you are not much more innocent than YU
