I honestly believe that such behaviour is caused by the fact that the game industry is relatively young and grew up in a relatively awkward way.
Back before the 200x indie boom, the barrier to entry was very high, and in some cases close to insurmountable.
Gaming was a niche, and by and large gamers were "hardcore" gamers, somehow expressing their (our) appreciation by considering the famous names (Miyamoto, Garriot, etc.) as actual idols, basically rockstars that the outer world had never even hear of.
That (my) generation grew up dreaming of becoming game devs, only few got to, and some of them became entitled.
Suddenly they only knew what was going on behind the scene, and everybody else had to STFU.
These people now are completely convinced they know better, even if their (legitimate) point of view is often more narrow (or biased, or oriented to something else) than ours.
So on one hand they managed to get where most of us couldn't, and therefore they think we don't know shit and we need to just buy whatever crap they tell us.
On the other, they never had any manager handling them. There's a reason why most old-school devs are generally nice persons compared to new ones: it's their social media manager talking.
