Disney's Form of PC

The Disney Virtual Kingdom is on-line. It has a filter to protect the kids--from all sorts of words, but not all of them are words you'd normally consider unsuitable for children's ears:

Because the Disney experience is supposed to be kid friendly, interpersonal communication is limited to a pre-approved vocabulary, so words such as "rebellion," "love," "obey," and "usurp" are just not allowed.

Is "obey" in the list because children shouldn't obey their parents? Or is Disney concerned it could be slipped into sado-masochistic dialogue? We're guessing the former.
