Yep. This is why I don't have a cloud-based digital library. UV offered a way to migrate to other providers, but will the next one? I don't know that they're legally allowed to. What if the other provider doesn't have the content, am I SOL?

I so badly wish I could buy a license to get a specific piece of content, get a copy to play on my own computer, then also have the ability to "upload" (aka, unlock) that content on a cloud streaming service of my choice.
