That's a weird comment, sounds like there was a lot of corporate bullshit in the background. Maybe he didn't expect meddling in a website he founded, mentally checked out a few years ago and now finally had enough. That buy out a few years ago was a disaster.
It's most likely that he doesn't have the control he (or any of the old guard) wanted.
Giantbomb worked best in a dedicated physical space, which got upended for COVID (which I have no idea why, it's not like 4 people in a room broke any kind of protocols). It sounds like corporate really liked the idea of not paying GB's rent anymore and decided "no more physical space" and "just stream from home" became the new mantra, leading to a much worse product. On top of that - it looked as if both companies (GB and GB's owner) invested $0 in everyone's WFH setups so it looks completely like amateur dogshit that devalues the product even more. This probably accelerated the "Nextlander" split, with Vinny and company realizing that if corporate wasn't going to invest in the product - they could just do their own twitch streams and not have to kick anything back to a bigger company.
Giantbomb has been crazy, their hiring has almost entirely been dogshit - they have two full time producers but the streams still look like inconsistent garbage, they're trying to swing around to becoming a "podcast network" and using "part time friends". I'm sure corporate had all kinds of suggestions but the core of it should have always been "get some likeable people together in a room", and it sounds like it wasn't going to be that ever again.
The press release mentions nine "core" GB members, but I can't even name 4 of them - and the idea that Voidburger or Matt Roarie would be "core" is kind of insulting to the concept. Giantbomb is officially dead, but it died a brutal death years ago and people are just finding the body now.
I sincerely wonder what Jeff does next, if he even has the energy or drive left to start something new or if he's just going to try lazy twitch streaming or mediocre corpo job.
