Jason is uncovering some shitty practices within the industry (though, it's the same in IT in general but that's something else). Said companies might decide that they don't "support" Jason anymore and he could decide to uncover a lot of gaming secrets.
Though, generally, there's NDA all around. Back in the days, some gaming companies public FTPs were full of uncovered stuff and folks respected that.
I think Jason notoriety is quite big, not sure he requires companies "support" that much. But it's not the case for every gaming "journalists" or whatever title you want to use in here.
