Amazon recently announced their "Sidewalk" initiative, where they will use your Echo and Ring devices, and a small part of your Internet bandwidth, to provide you, and others (that's the rub) with better Internet connectivity. Aside from the inevitable security breaches this will create, the real issue is that Amazon is going to automatically opt you in for this sharing instead of asking your permission.
I say nay nay. Not going to happen here. I went into my Alexa app and disabled the "feature".
