What you’ve mentioned has limited impact on a quality product. I’ve already addressed everything, including how it won’t affect star ratings, and you know it’s a small group of people causing trouble for everyone. I believe you’re still exaggerating and overreacting to the impact on the vast majority. Regardless, I’m glad to see feedback like yours on marketplace practices and hope they take it seriously in the future by finding solutions rather than passively removing all text reviews and sacrificing all users’ rights.
I haven’t used Unity yet, but I recognize the strengths of its engine. If they communicate more effectively, why wouldn’t I consider switching? For example, at least they improved their pricing model after criticism from users, unlike FAB, which refuses to make any changes by far.
