I think it's entirely appropriate to call someone a hack for taking a vacbed and claiming to be an innovative artist with it, like as if that's not just every other thursday at the kink club.
And the same also applies to non-rubberists who make pieces with rubber.
It's straight up pedestrian, even plagiaristic, especially when they're so vanilla that they don't have a safeword and give a release to the "artist".
And it sucks major ass how they've basically stolen kink from us.
