I'd personally argue that reporting on the existence of unannounced games doesn't do much but instill early expectations from the fanbase which ultimately leads to a game not hitting those expectations.
There are times when reporting on leaks are okay. To me, personally, reporting big details about Fallout 4 almost 2 years in advance is not okay. Nothing good came from that expect for website hits on Kotaku, hurt feelings, early expectations and disappointed developers. Sure, whoever leaks the stuff to begin with needs to just simply not do that, but sometimes reporting on leaks can do more harm than good.
Just my two cents, I guess. Boasting that you reveal games way in advance (which has a multitude of effects on the developer, the publisher, and the fanbase) isn't exactly something to be proud of in my opinion.
Features like those exposing work conditions at Rockstar are good. Acting like a victim because you front-paged something that was not meant for public eyes (and not for any sneaky reason other than it wasn't done yet and announcing a game is a huge part of a game's marketing push) is kinda off-putting to me.
