Not really. It's a red herring.

Suppose for the sake of argument that every review in the App Store for every app was like the one in the screenshot, a complaint about ratings requests. How would that be helpful? How would anyone know whether, aside from the ratings requests, the apps were any good or not? How would those be good reviews? You might defend the reviews as accurate and justified, but they would still be largely useless, because they're so narrowly focused.

I'm happy to receive 5 star reviews for my apps, but honestly, some of those are poorly written too, overly vague, or too narrowly focused, occasionally inaccurate, claiming my app does something it doesn't actually do!

The underlying point, though, is that Apple is relying on user reviews as a poor substitute to cover up its own shortcomings in reviewing app submissions. If an app doesn't do what it says, or it's user-hostile in some ways, how are those apps even getting through to the store in the first place?
