Retsupurae, starting out as "let's make fun of shitty LPers content/characters" rather quickly gathered a LOT of trollshielding, unlikable cunts for fans such as
PressFartToContinue and a couple smaller personal lolcows; and while a few "your content is garbage lol" comments on a guys channel didn't hurt much if anything at first and was mostly drowned out by people spouting positive themed memes, it quickly grew to 20-40 rabid 13 year olds screaming "KILL YOURSELF THE INTERNET DOESN'T NEED CONTENT OUR LP GODS DISAGREE WITH" on the Retsupurae subject the second any video that didn't have the video creator's identity censored out was uploaded, and continued even when they started editing in messages pleading for people to not go leave shitty comments over the edited out names.
this + slowbeef migrating away from video production and moving more towards streaming culture alongside the gamergate happenings was the start of SB getting really chummy with other members of "the industry" (including meeting Zoe Quinn around that time) and other SJ-centric something awful LP members that are of the "correct" politics and attitude groups towards certain issues, potentially cause he feels guilty or partially responsible in some way for the online hostility and needs to surround himself with more "nice people just trying to be inclusive and caring" to avoid ejected from his new friends group as a hateful male cis het child-bearing shitlord, especially considering his highly problematic past where he'd readily call someone a faggot and tell them to kill themselves for a joke.
i don't know if he needs these mostly unsuccessful to low-level success industry people to get anywhere in the business considering he has a long history of mobile software dev work with real companies that possibly matter and has spoken of being part of large-scale product launches in companies before, so it's unlikely to me that he'd be rat king farming in some gambit for popularity, contacts, and financial success; the game devs he know mostly are unprofitable drama mongers, and the rest are all low-rank videogame reviewers and written content makers in an online social climate where that's less valued than it's been in a long time. hell, even with LP and RP fame alone he could get a kickstarter funded really easily if he managed to make a half decent product.
writing at polygon is probably just an extension of when he used to write frontpage articles for SA, dude probably likes to be heard and have his ego stroked by having his content be seen like most people; polygon is also like 10x more popular than SA is now and i imagine beef isn't going back to daddy lowtax after he hurt his LP friend's sadbones with his horrifyingly pedophile-negative parenting. all in all it looks to me that he's (in his nearing middle age now parental brain) migrating from the dying SA community climate of "the old days" to what he probably sees as where modern internet people just congregate now, it doesn't help that he had to mod a place that was basically converted to a social justice climate by what they see as the "young, hip, inclusive women of color" and "brave B R A V E troons"
(1 or 2 LPers even went through temporary troon conversion only to backtrack) driving out the "older bigoted hateful people" and is trying to be remembered as one of "the good ones" by the new community.
or he could just be a bit of a faggy cuck and care about the way loud cunts with bad hair think of him before his own actual thoughts and opinions, i don't fuckin know i'm a guy with a wrestling chihuahua avatar on the internet not his dad
(but i might just have written more about him than his dad has in awhile)
