What's really sad about that video are all of yesterday's speedrunning stars that we just don't see at GDQ anymore because the atmosphere of the event choked all of them out. Present during Naegleria's bonus stream "run" are Peaches (bald guy with black beard in back left of shot), Blueglass (socially awkward guy wearing plaid on couch), Withhelde (in the red dress on couch), Trihex (sitting behind Blueglass wearing green shirt), and of course Naegleria himself doing the run. The only person present in this video who is still a major part of GDQ today is Spikevegeta, who is sitting behind Trihex (he's wearing the blue shirt).
Naegleria was "too hot" for GDQ, his last appearance was AGDQ 2015 where he was part of an F-Zero race. Trihex became too big to devote time to GDQ, he last official run for the event was Yoshi's Island at SGDQ 2015, though he made an appearance during the Super Mario Maker race at AGDQ 2016. Blueglass was never an official runner at a GDQ event (though he did run Ecco the Dolphin before Naegleria's Sonic run in the bonus stream) but he was a personality that everyone loved; however allegedly his presence was deemed "too annoying" by GDQ staff who no longer permitted him to sit on the couch and pushed him further and further back into the crowd. He can be heard laughing throughout AGDQ 2016, but has not been seen at a GDQ event since then. Withhelde, who is actually a respected transwoman who doesn't shove it down people's throats and claim persecution from danSexy emotes, last participated in SGDQ 2013; it is believed that one of the reasons she stopped attending GDQ events was because of their rules regarding props such as plushies (which were her trademark). Peaches simply became too busy with life to continue speedrunning I believe, he was most active around 2013 though he did come out of "retirement" to play Catechuman at AGDQ 2017.
There's a lot of talent pictured in that room and virtually all of them with the exception of maybe Peaches were driven away by the shitty executive decisions made by GDQ staff. People talk a lot of shit about how GDQ is trying to "be inclusive" and refers to people like Protomagicalgirl as a "diversity hire"... but they already had the diversity all along. They had transgendered runners, they had minorities, they had autistic/neuroatypical people. Good people, too. And they chased them all away to replace them all with cancerous versions of the same thing.
