The point is that the artist is re-drawing "based" on elsa in his style and for us to have H content about it (I'm not sure Disney will ever do that ><). Having a GF which is an artist, it takes ages to draw something and even if it'a a parody or whatever, big work has been done and such.. And and the end of the day, all of this is original content made by the artist.
Regarding BB, idk as I only played the original BB but the games out there are extensions "based" on the game with new story, extra content as I understood.. That's legitish for me.
Regarding this game, that's the exact same story that the artist done, animations are not from the dev etc...
I think that only the coding and (maybe) translations are original content, everything else is stolen. At the end, nothing more have been created, only stolen content and a biased Patreon button to gain money from it, that's not legit for me.
BTW, that's an interesting subject to discuss on F95 I guess. Idk if you got my pov ?
