Buying digital copies is the same as renting, and also carries risks. We've all seen platforms remove titles, and my digital copies aren't safe despite spending my hard-earned cash on them. It's easy to get confused because streaming services market digital copies as one-off purchases and hide the terms and conditions in complicated user agreements that we don't bother reading. If we did read them, we'd understand that digital media purchases can be canceled or revoked at any time without compensation. You can also use platforms like Movies Anywhere to transfer all your digital movie purchases into a single library for convenient access.
