Because attacking and "vilifying" the press is what Trump and the far right does.
I really think it just goes that far.
To be fair I do think that the long disdain for the videogame press was a fertile soil for Gamergate. For years a lot of people used interchangeably "a bunch of incompetent, sycophant elevated fanboys mostly acting as glorified catalogs" and "BOUGHT AND PAID FOR BY THE GLOBALISTS PUBLISHERS" which is more incendiary and was, for some, easily mutated into buying hook, line and sinker that some indie dev fucking some writer was a MASSIVE SCANDAL proving that those incestuous elites are in a cabal to transform the proud hardcore gamers into sissy giant dad SJWs. It's undeniable that this is the classic far right narrative on "media" or "Hollywood" being reskinned for videogames.
Not that it warrants the endless shielding from criticism but to be honest gaming forums probably needed to mute the usual console war rhetoric a notch.
