Not to mention how he's basically blacklisted from the industry for being so uppity, all his contacts are either gone or leaving.
S'not actually so much for being all uppity - Jim is anathema to any movement, reveal, promotion or position as he inevitably makes it all about him.
If you want to reveal something important, you want to send it to someone who can express and contextualize it. This is why the handful of decent investigative journalists out there in gaming get basically all the backroom info - Its never about them, its always about what they've got, and the four other pieces of stuff that wasn't relevant to the conversation until this new reveal came, and they bring it out all at once. They sit on the info instead of waterfalling on twitter over the slightest leak, prioritizing a good story over immediate asspats.
If you want to promote something, particularly review copies, media contacts for questions, etc, you want to give these to creators with passionate fanbases, creators with styles, but most importantly, creators who's style is to maximize engagement with a title in their own unique way. Think Spiffing Brit, who goes apeshit on examining all the fine details of a games mechanics, to find gaps and exploit them. You want someone who multiplies the titles charm, as opposed to simply commentating.
Jim doesn't meet any of these criteria - If a game is bad, he makes it about how shitty his life is instead of about the game. If the game uses mechanics or monetization he opposes, he makes it about how he was right to highlight X flaw in the industry and its getting worse and all this is pointless because his life is shitty. If someone reveals industry secrets to Jim, he immediately goes full blast with them to promote his soapbox about how the industry is making his life shitty. Anything of substance that is being communicated is smothered by his obsessions.
Jims a failed content creator and journalist as he's lost that distant position from which he had a personality to engage with a product in a distinct way, and instead is just using everything as a springboard to bitch about his life. Complaining is not creative, at the end of the day.
