@thomasfuchs First off.. who says this is "stealing"? Copyright fair use is a thing.
Also in Japan it's not stealing:
“regardless of whether it is for non-profit or commercial purposes, whether it is an act other than reproduction, or whether it is content obtained from illegal sites or otherwise.”
