Netflix is not one key per user. It's one (or more) keys per title. But every user get the same key. What is describes in the post is NOT DRM. It is encryption.

- bscphil 8y agoThis right here. The closest this comes to DRM is that it's obfuscation, which makes it difficult to find the right download link. But once you have the right download link and you're logged in, it's trivial to rip the stream. Real DRM can't be broken without either a flaw in the encryption scheme or reversing the proprietary and closed source bit of code that handles the decryption. In other words, if you want to have real DRM, you have to use Widevine or some other browser-supported scheme that you trust.
