That's why I don't really care that much about terms and conditions. Just because they say they can doesn't mean that they will, conversely, the writing can be misleading to anyone who isn't a specialized lawyer, so most people can't really tell what the terms and condition let them do anyways.
I usually go for reputation and precedent rather then legalese. And in the case of Disney, they had ads in their video tapes and DVDs, so I don't need to read the user agreement to know that it has a good chance to come to Disney+, whatever the legal pathway is.
