It's a common phenomenon that when something becomes widespread, it automatically becomes controversial, mainly because those who create controversies about it are the ones who want attention since they know they are going to get that because of the fame the thing has got, which they are creating controversies about.
OP's case seeems to be the same to some extent. He probably had tried getting into a signature campaign himself. Still, he couldn't succeed, so he decided he would get some attention by trying to take the name of Signature campaigns by saying something negative. Even though he failed to get a signature campaign, he did get enough attention from all of us so his tactic actually worked.
OP is a newbie, he couldn't get into a signature campaign a priori. So I don't think his motivation for creating this topic is related to that, unless he's completely unfamiliar with the forum rules. In this topic he may have attracted attention, but it is unlikely to pay off for him in any way, because here the subscribers themselves discuss more than they answer directly to OP.
