Initially I was against it in your first paragraph but I started to agree. People do go out of their way to leave a bad review, the others are left enjoying the product (most of the time).<p>The only moral issue is perhaps that the method doesn't disclose what people are unhappy about to the public, who might be looking at the reviews. However, you're not preventing people from leaving a negative review with criticism, you're simply providing a way for feedback to be provided directly back to the developer which is good and there's no issue with that.
> The problem with ratings and reviews is that they are inherently negatively biased.<p>I read in behaviour science that a negative experience outweighs a positive one by about 10x. Which makes sense when you look at the origins of humanity (potential danger of predator animals, enemies, etc).<p>Yet, I found the post quite low on details on the actual implementation part, like it were a secret.<p>I assume, it was just the same technic mobile game apps where using already more than 10 years ago: Show the user a rating popup (survey), if they rate low, send the rating as feedback internally, if they rate high, forward them to the app store rating page.
