Nintendo of Japan doesn’t file lawsuits against DS emulators either. Sony is a Japanese company; they sued Bleem and lost but that was more than 20 years ago. There are emulators for PS3, PS Vita, and PS4 - all platforms for which Sony still hosts network infrastructure and operates digital storefronts - and AFAIK none of them have been subject to legal threats.
