Keep Quiet?

[Mike M]

I am starting to get an occasional Varsity HS ball. In the previous inning, a close play at the plate and the manager argues the call. PU ends up ejecting the manager and assistant coach (they both deserved to go). With R1, pitcher straddling the mound, he fakes a throw to 1B. PU calls balk even after the pitcher tells him he was not on the rubber. PU says it does not matter, it has HS rule that you can not fake a throw to 1B, even when you are off the rubber. Since PU has ejected the manager and assistant coach, no one objects and I keep quiet. What would you have done?
