> you will no longer be able to watch any of your previously purchased Discovery content and the content will be removed Content you purchased. Their wording. Not content you rented, not license you paid for. They are effectively stealing the content you purchased.
You don't actually "purchase" physical media. It's still licensed. The question for digital purchases is how perpetual the license is. This is different from Spotify and Netflix where you clearly are renting it, and there's no confusion over that.
Clearly there are restrictions to what you can do with it (duplication, public performance, and so forth), but those restrictions are defined by copyright law. The notable exception is software, but it could be argued that licenses were a product of the need to duplicate software (e.g. install it to a hard drive). That said, modern software licenses do go far beyond that.
Then again, I may be misinterpreting the meaning of license. I have always views them as modifications to the rights granted by copyright law.
