Ring adds end-to-end encryption to protect your video streams

I bet my bottom dollar there's a back door on the encryption and the NSA has the key.

"Currently, Ring videos are encrypted in-transit when going from the camera to the cloud and while they reside on the servers. However, video streamed from the servers to a device are sent decrypted. Ring has simply added an extra layer that encrypts the video all the way to the receiving end." WHAT?!

Should this not have been there from the start?
