I've already given up my location data to Google by using Android with Google's services. It's fine if the doorbell sees me entering and exiting. By adding the doorbell, my threat surface isn't expanded by very much, but I get all this extra doorbell utility.
I don't really have a problem with Google seeing the outside of my home. I wouldn't put a Nest camera inside. Personally, that's my line. The important thing is that I can change it later if I want.
As far as your rights, sure, sue Google or Amazon if you want. It's not really my problem unless the devices get banned, which won't happen. If they do get banned, I'll replace them with whatever the next best thing is, or roll my own.
I understand the frustration, but at this point, the only rational thing to do is adapt.
