The people that do this sort of crap either don't care as long as they can make money of of schmucks, or they don't realize that the people that CAN translate don't NEED to do it because, guess what, they can understand Japanese.
Which means usually they're motivated by getting their translations out for other people to enjoy.
Which also means that if peeps are satisfied with garbage, they don't have any motivation to translate properly for the few people that are left which don't touch the MTL garbage.
