Stop the negativity! I don't think it's their fault. The more likely reason is certain music rights-holders and celebrity estates refusing to grant Disney the licenses that they need in order to release the rest of the show in its entirety. They don't want another fiasco like the one they did with Season 1 (where several songs were cut out due to music rights that could not be cleared). It's the copyright-holders that are at fault and they've obviously kept on making Disney break their promises.
