Sony announced on Monday that it would remove all Discovery content, including shows like “MythBusters” and “Deadliest Catch,” from user libraries, even if they had been purchased on the PlayStation Store.

The company, which owns and operates PlayStation game consoles, said in a brief statement that the Discovery shows would be deleted on Dec. 31, attributing the decision to “our content licensing arrangements with content providers.” …

Some PlayStation console users expressed frustration with Sony for taking away content that already had been purchased. One user posted on social media that they were expecting a full refund for products bought on the PlayStation. Another wrote that the message from Sony to customers was essentially, “If you ‘purchased’ any of these titles via PlayStation, they are going to disappear soon and too bad for you.”

[That’s exactly what it means. If you purchase movies or entertainment virtually, you really haven’t purchased them at all. You’ve only rented them at the purchase price. That’s true with Amazon and other online streaming services too. I suspect some enterprising lawyers will quickly turn this into a class-action lawsuit, but in the meantime, don’t “purchase” titles unless you’re buying them on Blu-Ray or 4K media that you can keep in your hands. — Ed]
