I used to work for a well known communication app, the kind everyone here used. Couple things I learnt about "end to end encryption":

- You can call your service e2e encrypted even if every client has the same key bundled into the binary, and rotate it from time to time when it's reversed.

- You can call your service e2e encrypted even if you have a server that stores and pushes client keys. That is how you could access your message history on multiple devices.

- You can call your service e2e encrypted and just retrieve or push client keys at will whenever you get a government request.

We already 100% know this is misleading though. Amazon has access to your ring footage.

They are acknowledging that the end to end TRANSIT is encrypted. They are not encrypting from themselves at rest.
