Hmm. My little sister watches all her Disney tv series on YouTube and she doesn't care how awful the quality is. Sometimes I'm appalled how she can watch Princess Anna (??) in a small screen, at 240px and x2 speed.
As for Disney movies, we tend watch them in cinemas, and if they're really lovable, get them on DVD too.
I get that Disney wants their own ecosystem but I think this one may be redundant. We already fork out monthly subs on Netflix and Amazon Prime (lets not forget Hulu and others are beefing up too) and at least, these services cater for both adults and children.
