Strongly disagree. Their features are really good and no one else in the mainstream games media has reported as much as them on working conditions, failed projects, and so on.
If anything, more sites should be like Kotaku with the way they've been running things.
If they are guilty of anything it's maybe feeding into a 24/7 news cycle with rabid ADHD-laced authoring (same writer hates this game they loved yesterday), regurgitating content to pad the page, and I suspect some articles probably being written under the influence of booze since they can read about like my own drunken logic. They're human and they're trying to generate revenue - it's all good.
