As someone who publishes to both F-Droid and Google Play, I can’t count the amount of times I feel regret for having spent any time coding because of certain people giving 1 star reviews on Google Play because one minor thing isn’t as they want and being extremely rude about it.
I understand ratings can help to give a better idea of what you’re going into, but the way it works on Google Play is EXTREMELY demotivating for developers like me.
