You have to understand that most of these studios are now run by people 2-3x the age of the average gamer and are so out of touch with what makes a good game that they simply bark at them to make more money. A lot of studio's are under so much pressure to deliver increasing bottoms lines for stockholders and it inevitable will make them crumble.
Studio's being bought up by larger entities is just how it's always been and as you've seen it often results in shitting out increasingly worse games until the studio is closed.
I mean look at Battlefront 1? It was a terrible game because Disney and EA forced DICE to release it in under a year to be timed for the movie. Nobody gave two shits about the quality of the game, they just wanted to get that sweet sweet movie game hype money. Hype money that fans had been waiting for over 10 years for a new battlefront game only to be laughed at.
Dawn of War 3 was the same thing, the fanbase for Warhammer is insanely passionate and often loyal and that's why the moment they shat out a terrible game it was practically dead in the first week or so of launch as fans dropped it.
We have to scream louder, it's the only way companies are willing to listen. But also involves witholding your cash and stowing your wallet! Look at Total War Warhammer, SEGA must be fucking reeling at LISTENING to fans because it's their top earning title and it started off with a massive backlash on how Chaos was going to be DLC.... years later.. look at them now.
You do have a point, but I for one wouldn't mind for the old guys to keep their positions as long as creative freedom is given to the developing team.
And believe me I tried screaming, yelling, crying, chasing... I'm done with that, now I deal in action.
