By the Wikipedia definition their Gamergate article probably is fairly objective, which makes it a bad example. They base their coverage on what news media report, and the news reporting on it was not exactly accurate or honest (which seems to be what you get for going against journalists).

For instance, gaming and tech publications spent a lot of words trying to associate Gamergate with the use of swatting to drive women out of gaming. This caused much confusion as to what they were even talking about, because pretty much all the swatting attacks against gamers had been targetted at guys as far as anyone knew. A few years later, some guy with (as far as I know) no ties to Gamergate that anyone's been able to find was arrested for a series of rather misogynistic swatting attacks against women gamers that the press had known about but intentionally hadn't covered. They'd literally been trying to blame Gamergate for a swatting campaign that none of the people they were blaming could even have known existed because the only coverage was the vague and cryptic attempts to blame a completely unrelated group of people who'd criticised journalists for it.
