We are heavy Alexa users, even our lights are controlled by Alexa...but with switch backup, my hubs is all about redundancy. But he is highly techy, so we have every device known to man LOL And if people are scared by that, if you use an iphone or Samsung phone, you are being tracked, watched and recorded in some cases, so using Alexa is no more of a threat than carrying around a phone, who doesn't.
