He doesn't care about you releasing characters. It's really just a respect thing. Just as MA takes permissions for everyone stuff, takes away our opportunity to do so, much like anything pirated. He wants everything related to their stuff be as it was released by "them", open source. I get it, especially when its original sprites, etc. Not owned by any company. It sucks, but, if you don't pay any mind to it, it won't matter. This is literally what mugen is. You can't stop it once its online. Aye & I know it feels like "it doesn't matter" "he is overreacting" let it happen to you & see that it doesn't make you feel some type of way, justified or not.
