maybe he should have done something about it in like 2010...or 2011....or 2012....or 2013....really, at any point in time, he probably could have contacted someone and been a pain in their ass until he got his credit.
Beyond that, it doesn't even seem like it would have taken much work to get attention. I mean, all it took was a blog post and Gerard heard about it within 24 hours
. Would that really have been so difficult five years ago, when it would have made sense to bring it up?
Plus Gerard seems like a cool guy. I don't know a ton about him, but he's a fellow artist, and I know art is important to him; it doesn't seem like he wants to rip anybody off. Sucks that the guy hasn't gotten credit for it, but this is a strange way to deal with it.
