Zoe Quinn was dating a guy.
Guy found out Zoe Quinn was cheating on him with at least 5 confirmed other guy.
Guy made a website where he explains that she's a total slut and liar and people should be wary of entering a relationship with her.
One of the guy in question was a Kotaku reviewer (Nathan Grayson).
Somehow there was misinformation about him reviewing Depression Quest (which he did not, but he did write about Game Jam where it was mentioned as one game present although that was before their affair anyway)
People are outraged at how Zoe Quinn slept with the press for better reviews of her free
game. (which is based on misinformation - see Klutz above lol)

So other than being a terrible person, which there are plenty of in this world, there's nothing really special about her.
