It's meat. It's already dead. You can't be cruel to something that's already dead.
And it's not going to encourage the mass slaughter of more animals. The only way to get efficient energy out of any agricultural product — especially something as expensive to produce as meat — is to use waste byproduct like this.
Animal rights groups waste their time on perfectly reasonable animal usage like this when they should be focusing on real cruelty issues. It distracts from genuine, solvable problems and undermines their legitimacy.
Personally, I'm going to be first in line once vat-grown meat becomes commercially viable. These clowns should be doing all they can to promote the research and marketing of such technology.
