It's worth seeing how gamergate describes itself. The "what is gamergate" column on the sidebar of a subreddit where they hang out[0] might help there. Do note that I do provide the hyperlink, but I do not endorse either front.
Those posts are almost exclusively about media bias, manipulation and censorship. Isn't that what GamerGate claims to be about?
In the top ten, precisely one item (number ten) is about video games.
GamerGate is about more than video games, it's about media manipulation and bias and it's about journalists acting like activists.
Also if I recall correctly Rotten Tomatoes removed the ability to submit a review for a movie that hasn't been released yet, which to my mind seems like an entirely sensible restriction, particularly in the face of the obvious spamming that was going on. It seems to me like RT made a product decision relating to what best serves their users. What's the argument against it?
This is silly. They locked out reviews being placed before the movie was released in theaters, because the rating was being deliberately bombed towards the single digits by people who can't possibly have seen the movie.

Does that review sound like someone who is upset with a movie studio because they created fake outrage, or someone who is upset about a movie's female lead?

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.
