1. We don’t know what the Gedolim said about this.
If you hold the titular roshei yeshiva of BMG to be “Gedolim” (one is on the “Moetzes Gedolei HaTorah”), then the Gedolim approve of the development.
2. Even if the Gedolim gave their approval (which we don’t know), I’m sure they never said that this has to happen or that someone is not allowed to protest.
3. She certainly has a right to speak to Roshei Yeshiva about it and express her opinion.
I’ll remember that next time anyone brings up “following the Gedolim”. I certainly have the right to protest and fight their shittos until I have the time to discuss the issue with them directly, without an intermediary. Looks like I get to vote Meretz after all 🙂
