I think some issue is that people here say "gamers" don't like it when KIA is but a fraction of all gamers, no Im not counting mobile players, so there are some gamers who love it.
People on both sides are taking pot shots at the other, instead of just ignoring each other and playing what you like.
As someone who jumped to KIA2 upon its creation I saw what lack of moderation brought, and yes it was literally idpol bullshit. Instead of admitting it or , better yet, fixing it the KIA2 mods decided to sweep it under the rug to prove their little experiment was better than KIA. Eventually AOV let power go to his head and forced "troll" flairs on users who deviated from the groupthink. KIA2 is the mirror image of SJWs.
Adam's sister has a blog going back to 2016 where she wrote about being a sexual abuse survivor. In a 2017 post she says her brother was her abuser, but doesn't use his(Adam Savage) name. This isn't to say she hasn't been lying all these years, but it isn't a new allegation from her.
Puppeh claims that when he was a 14year old Smash player, 24 year old Cinnpie sexually and emotionally abused him.
Here are some Tweets from a member of the Smash community showing text messages talking about the situation prior to this blowing up. https://twitter.com/HeroKillerH8/status/1218222010431680512?s=20
I would agree putting it on obvious troll would be amusing but AOV considers not agreeing with the herd to be trolling.
