I don't mind at all releasing whatever graphic I have done for Bitcoin in the public domain, it's just that I have no idea in which license is the original logo done by Satoshi, especially the symbol. Is that symbol in public domain? I know this may sounds dumb, but it has to be, right? If it is part of an open source project. I am no lawyer or programmer familiar with this sort of things, I am just a bum for god sake. So perhaps someone can enlighten us.
Well, Japanese people can't release their under public domain. Japanese copyright law forbidden it. Unless, Satoshi lived in the states instead of Japan or I am misinformed about Japanese copyright law.
