Monica has been wronged. She uses her real name here on Stack Exchange, and anyone who knows her, including prospective employers can easily find her internet presence. That presence has been smeared by Stack Exchange, with unfounded accusations, that were even published in the press. The defamation needs to be retracted, and an apology issued, as this is going to do lasting harm to Monica.
Stack Exchange are refusing to acknowledge any wrongdoing, either for legal reasons, or through sheer stubbornness. They are hoping that if they ignore this, it will just go away.
So, to answer your question:
Does repeatedly talking about Monica actually do her any good?
We should not allow Stack Exchange to simply ignore this matter. By keeping the discussion alive, and raising awareness, we are greatly helping Monica. She has been wronged, and the Stack Exchange network is being harmed by the very people that run it. By helping Monica, we help ourselves, and we help the long term future of the network. We should not allow bullies to prevail.
Stack Exchange have picked on Monica, because they're a company with a huge budget, and she's just an individual. They thought they could squash her, with no consequences. Now that the community are pushing back, they have done what bullies do when confronted. They've run away.
We need to make sure this issue does not get dropped until Monica's situation is resolved, and measures are put in place to prevent this kind of abuse of power from happening again.
Remember, there's nothing to stop this from happening to any of us, all it takes is a whim from the powers that be. Do you really want to just let that slide?
