Okay, so I don't really understand any of these relationships, but I really don't understand what this Shane guy is arguing with the Gizmodo guy about? Like he seems to not want to be associated with Jontron, but his twitter header has multiple images of... JonTron? Like he seems to be fighting just to be fighting, definitely concerns me about his true intent.
Jon and Shane are longtime friends (probably one of few people on NormalBoots he hasn't had a falling out with). His issue with the article stems from it's claim that Jon has a reach of 12 million subscribers when you factor in channels like DYKG, PBG and also Game Grumps, all of which except the lattermost are a part of NormalBoots.
I believe for the most of the part he's just protecting the brand from a situation they had no involvement in, which is somewhat understandable since both PBG and Jirard seem to have gotten a whole mess of people questioning their worldviews because of their direct association with Jon.
