They didn't hate the conference at all. The hyperbole is embarrassing. They were definitely impressed by the new direction of God of War, they loved Horizon, and a bunch of them were on-board with Detroit. A lot of the stuff they weren't super hyped by, like Scalebound/FFXV(and even grumpy Gerstmann himself said the game looked better in other trailers) Days Gone/all the VR aside from REVII/whatever the fuck that was from Kojima, is stuff that a lot of people on GAF were iffy about.
And I was definitely one of those who felt they bagged on last years conference a little too much, but I can see their perspective on this. It's not their place to get super hyped on stuff that's YEARS away from release. And nothing here was Earth-shattering. People are just giving in to hype.
Also, they're all allowed to have individual opinions on things. FFS, this thing featured God of War AND something new by Kojima and if Dan still felt it was weak, you can't say he's been blinded by his bias there.
Their criticisms on some of the presentation aspects were on point too. The stuff around the VR/COD stuff was super confusing and getting someone to introduce COD/segue off VR would've helped. And they know VR generally demos poorly, but they discussed the benefit of an on-stage VR demo for something like Farpoint is to showcase how intuitive the shooting mechanics would be with the move controller, something that isn't visible strictly through a first-person demo.
Everything they discussed was rational and made sense. But leave it to GAF to blow up over nothing, just because someone didn't love someone as much as you did. As if you need your enthusiasm validated like a child.
