Depends on your own personal convictions. Once they have your data, they have it (unless laws come about forcing them to delete it, which is unlikely)
Personally I’m staunchly against it. Even Ring doorbell as well, they are rumored to begin using facial recognition and scan license plates. Too Orwellian for me.
My parents are surprisingly modern with technology, so they have Alexa in a few rooms, with most lights connected, and their garage.
Siri recently had a whistle blower contractor state they hear snippets of intimate conversations/sounds, with Siri not supposed to be activated.
These devices always have to listen, and for them to get better, the supervised learning must have a human say “yes/no” if the predicted output was correct for the input (in this case, activating on “Hey Siri”)
Some open source home automation systems are gaining traction, and once they’re a bit more mature, I’ll self host and begin my voice-assistance adoption. But until then, I’ll stick to the old ways :)
