LOL, game devs don’t care about steam ratings? Brats raging all over on steam? Using that logic, none of the games on steam would ever get “Overwhelmingly Positive” rating. However, there is quite a lot of popular games on steam that does have that kind of rating. Developers constantly try to make sure their game get a good rating or they will fall into obscurity. So please, think again, yes there are joke/troll reviews, but there really isn’t as many as you think there is, and if the game really deserves a praise, you will see a lot more positive reviews in comparison.
And mixed reviews is a really bad rating, most of the time when a game is bad, people won’t even bother leaving a review for it, they will just quit altogether. I mean why go thru all the hassle leaving a review, those who are actually leaving a negative review aren’t raging brats you claim them to be, they just want to make the game a better place for everyone (Be it their suggestion is reasonable or not, not everyone is an expert on how game industry works). I don’t even know why you guys are fighting against them.
And if the game is good, far more people would like to leave a review for the game because they want more people to play with them.
TL;DR
Devs cares about steam reviews, the game get what it deserves for their steam rating, regardless of there are a lot of trolls or not.
