Oh, I follow now. The way I read it initially it was that fans were mad about it and they got it changed, not that they made it themselves. Thanks for the clarification!
Hmmm looked around a bit online and I couldn't find this edited image or any comment about Rockstar changing the cover art from the left to the right. I'm wondering if this is even real, or am I missing a joke? If it is real it's silly but if it's not it's just fake outrage.
