What he should do is target the overwhelming majority of apathetic people in the middle; that would garner him more attention/hatred.
Yep. Guy had his fifteen minutes of fame when he lost his real job after bashing his employers in his previous game, and now he wants it back.
I have to say, I think "they're only doing this for the attention" is a pretty pointless accusation, because it can't ever be proven one way or another, so why make it in the first place? I see a lot of people on every side of an internet debate throwing this around, and it just seems to be without value to me.
See also: "They don't really care about this issue" and "they're only doing this for the money," both of which are accusations made of people on any side of a debate, as long as they have a little bit of fame or income from their work.
When your argument revolves around your assumptions of how someone secretly feels about a given topic, I don't feel that's a very strong argument.
