It's not that black and white, I don't think.
It would be one thing if every now and again, LBB gets tired (let's face it, it happens!) and can't hit the note. Completely forgivable, IMO.
But this seems like more than "once in a while". If LBB is hurting vocally, something needs to be done about it. You wouldn't keep a star baseball player in the game if he broke his ankle, would you? You may not FIRE them, but adjustments are made for the situation.
If LBB truly carries the show, I would expect that something needs to be done (I think she knows when her voice isn't up to par), and approach the appropriate person (it seems like from previous posts something WAS worked out with the...composer? musical director? but the producers are having none of it.) It doesn't need to be on the extreme - to the point of being fired/resigning, but hardly noticeable tweaks aren't going to KILL Legally Blonde...especially if it's just "one note".
Personally, I wouldn't want to be in a situation where the higher-ups don't have my best interest in mind. But that's just me. Everyone has different goals. I'm not saying that LBB shouldn't be on Broadway, clearly she's made it this far. But is it worth risking what sounds like her current health and future career over it?
