That's probably best.

Backing away allows 'Jenny' to be the 100% complete owner of any future failure. If she runs off all the 'help,' there'll be no one left to lay the blame on.

This seems to be one of those situations where it's best for the OP to pick her battles.

At any rate, my advice stems from the fact that advice-seeking posts on GC are notoriously one-sided and probably omit important facts. I'm sure the OP will understand -- if someone has to post under a pseudonym, whatever they have to say should be taken with a hefty grain of salt.
