I also find this strange.
To me, the word "review" implies that I am writing for a general audience. This is distinct from "feedback" aimed at the developer. They have very different purposes. Reviews are there to answer the question of whether a game is worth playing, whereas feedback is there to help the developer grow by encouraging them and praising what is good about the game while still pointing out where there is room for improvement. Feedback should be gentle and encouraging when aimed at a newbie developer and highly critical when aimed at a skilled and experienced developer, but reviews should be the other way around.
I use comments for feedback and reviews for reviews, because reviews have a star rating and comments do not. As a result, feedback aimed at the developer is publicly visible and reviews aimed at the general public are not.
