Basically, the GG hashtag death spiraled after bit because of a few forces all agreed to "ackshully it's about ethics..."
Addict gamers who didn't want to go too hard against the gaming industry because they were worried about their precious franchise being hurt. They wanted to focus only on journalism and never on actually fixing games, to keep from hurting the industry.
Milquetoast libshits who couldn't cope with the idea that the whole thing was rotten to the core going all the way back to the entire civil rights movement, and just wanted to roll it back to the point where their favorite progressives stopped saying bad things about bideogames. Keeping it constrained to games journalism kept them comfortably separate from the bigger political or societal picture. These people mostly latched onto breadtube, because breadtubers may be disgusting slobs but at least they respect bideogames too.
People with parasocial relationships with Jewtubers, who thought that containing the criticism to just to written media like the Kotakus of the world would allow them to continue their imaginary butt-relationship with Angry Joe or Jimmy Sterling or whoever.
People who COULD NOT see for the life of them that ALL journalism was that bad. They admit good journalism is necessary for functioning democracy. But couldn't admit ALL journalism was just about as bad as Polygon, because then their precious notions of democratic norms would be called into question. So they wigged out whenever anyone brought up a non-game-journalism related controversy.
Autists who wanted an identity to latch on to and just eventually trooned out. 'Nuff said
(Separately, most ancaps got subverted during the whole Floydian Summer of Love, when the ancoms recruited them into their midst with anti-cop sentiment and the two became indistinguishable)
In other words, SJW-Lite was a union of a bunch of forces who just wanted to keep the conversation constrained. Keep you from advancing in level, as it were.
