Okay so after looking a bit into it, I think I understand what's going on. They don't actually like MLP, they're just looking to 'embarrass' the Hugo awards. Whatever.

If it's not about sci-fi, which is what the Hugos are for after all, then they could just take away the nomination as inadmissible.
