If you bought Disney movies from Amazon and keep them in your online library don't expect to watch them at Xmas as Disney as pulled them a lot of them from the library as they want you to watch them on their TV channel exclusively instead.
I came up with a good analogy to this. It would be like buying a car, but the dealer insisting that you keep it garaged at the dealership instead of your own home. Then on Christmas day, when you were planning to visit your relatives, you go to the dealership and find they are closed, and your car is locked in their garage.
This is why I resist to follow the trend of keeping things in the cloud. There may come a time when you really need something and find you cannot access it.
