Good point; I had forgotten about that when I typed the other post.
Disney signed an exclusivity contract with Netflix for the television-window release of their films. I forget when that is supposed to start (or did already?), but it's probably mentioned in the first article link to the news about these series. It does make sense from that perspective, though it still gives me a little shrug as to Disney intentionally putting obstacles in the path of a service they co-own.
