I think everyone stumbles about that "feature" here. Easy fix would be to rename it from review to feedback. Maybe it was planned differently and scratched for various reasons and reduced to be only to the dev. I do not understand why it is visible to followers. That should have been scratched as well.
Public reviews have advantages, but also bring new problems. Problems an indie platform might not want to deal with. A dev has complete control over comments, if desired. For reviews that opens a can of worm. If you give the devs control over the reviews, that review section is worth nothing. And if you do not do that, you have to moderate it and you can bet that devs will whine and bitch about "unfair" reviews.
