For Jsin:
Gamergate is a Consumer Revolt.
Short and simple.
Portions of it have evolved into other areas, but that is the core.
Another source, that I spend far to much time on:

For me:
I don't care about the drama. All I want is accurate journalism about games and game development.
I do not want game publishers to pay websites or magazines for favorable reviews for shitty games.
I want "journalists" to be held accountable for lying and collusion when they write articles favoring friends, or game companies that bribe them.
If journalists are being bribed, or are friends with a developer, then disclosure is needed.
If you want to get into the SJW aspect of things, and the 1st wave Feminists VS 3rd wave feminists, then I need more time.
