My thoughts are that every community has toxic individuals. That will of course spill over into the community itself. From the outside it can appear that this makes up the community as a whole, especially since social media and the media in general seem to want to highlight only this behavior.
I believe that a lot of the divide between gamers and developers at the moment can attributed to hype culture. No Man's Sky is a shining example of this. Promised to the moon, upon delivery it made a lot of people angry. You are free to criticize aspects of a game. It's an entertainment industry after all and you cannot please all the people all the time. I also believe DLC culture has a lot to do with it. I can't really attribute blame to a dev here but I sure can to a publisher that dissects a game to sell in chunks to the consumer.
It also has to do with a certain "pop culture critic" was being fetishized by the media. I'm sorry but labels like, sexist, misogynist, racist, homophobic get attributed to gamers as a blanket to demean the entire community. All because somebody bought and enjoyed a game with scantly clad women and some really bad jiggle physics. It's entertainment, fiction, taking up arms and shouting that exposure to these fictional worlds will turn your kids into any of the aforementioned is a vapid and baseless accusation.
The entitlement has a lot to do with the former. They beat a drum to make games more inclusive, your game, your way. A game for everybody is really a game for nobody. Due to varied tastes of gamers as I said before, you can't please all the people all the time.
I would also like to say that a lot of the problem in and of itself coming from people who don't even play games or rarely do. Professional outrage machines that see, scenes, dialogue, and what not and immediately take offence and start problems for everybody.
It's toxic on many levels. The thing we have to understand is that gamers just want to be left alone to play their games. We don't care if who or what that person is that we play with. When you take any community and endlessly batter them with degrading remarks and baseless accusations, you're going to get push back.
