I think encouraging people to enable E2EE is more realistic than asking everyone to throw out the Ring cams they’ve potentially spent hundreds on, yeah.
But... what makes you think that Amazon et al can't MITM the connection?
Sounds good from a security point of view, although it also says they disable functions like having more than one person able to view the camera (having a partner be able to answer the door seems pretty fundamental; they probably just can't be arsed to make such functionality work with safety turned on...)
Of course, just like with Signal or anything else that gets regular updates, they can push an update to your device specifically that sends the decryption key out. You'll always have to trust them to not do something like that, but that's a whole different level from subpoenaing data they have on a hard drive
