TotalBiscuit is a really interesting figure. He did a lot of good for the industry -- i'll never forget the person running the Warframe stream getting choked up when she heard the news -- but he also did a lot of bad. He was someone with a huge ego and his backing of GG is well known. It seemed like he was in it for the journalistic integrity stuff it pretended to be about, but even when the truth came out he didn't really back down. Even when women spoke up that he was causing a lot of harm and leading his audience into a toxic movement he didn't change course like he should have.
He was huge in the Starcraft scene, he gave a ton of visibility to Warframe, he was a huge proponent of consumer rights, but he also wasn't someone to look up to and his personality flaws and failings were on display for much of his career. He was an incredibly strong personality and that came with a lot of good and bad. He hurt a lot of people with his support of GG, even if in his eyes he was supporting what GG was veiled to be instead of what it actually was.
I'd be interested in watching a documentary if it was willing to dive into a complete look at him but i'm not sure this one will be it.
