>>96510067No, this is a totally different situation because 1. the original voice is Hatsune Miku and not Kaai Yuki (the controversy there being that Kaai Yuki is sampled from a minor and apparently there are terms of use prohibiting its use for anything lewd) and 2. it's a cover so it's sung by neither of them anyway.
The original controversy was dumb as fuck anyways, the creator shouldn't have caved unless the rights holder told him to (don't care enough to check if this was the case)
