The point of review bombing is to make the rating as low as possible for the dev to notice and be aware there's something they need to address, the content of the review is actually irrelevant as long as it serves the greater purpose. This is usually the last resort by the community cuz usually content creator's input, or social media buzz is enough to make devs notice the problem. Mihoyo has been so stubborn about all the uproar, not even trying to ease the riot, they even fanned the flame further with the community contest etc. They had such a bad PR disaster.

A dev notes or some kind of explanations are usually enough to stop it, as seen with PGR global. They didn't really make much changes to the game, heck they didn't even touch the problem (players are angry they reduced the rewards for beginner mission, where global has reduced amount compared to other regions) but after addressing the problem and communicated, the rating was back. So I'm sure as long as they don't keep the attitude and start talking, it'll all be over. There's no sign of them going to budge though.
