Right, but the point I'm trying to ask about is whether they're treating Ghibli specially here. People are reacting as if OpenAI is thumbing its nose specifically at Miyazaki here, whereas the impression I've got is that they simply opened the floodgates and dropped restrictions on styling in general.
Style has never been covered by copyright to begin with, so any concerns they might have had about being sued over style would have always been erring on the side of caution. They may simply think that the legal environment has calmed down enough that they won't be inundated with frivolous lawsuits any more.
Training doesn't involve copying anything, so I don't see why they wouldn't. You need to copy something to violate copyright.
