What if you bought the device just because it had this option? I have an Echo Dot 2nd Gen which I used for around two months, until it once failed at a command of playing back a radio station but instead started to continuously stream my audio to Amazon, for hours until I noticed it (bandwidth monitoring with InfluxDB and Grafana). Now none of my devices (phones and tablets) listen for hotwords, but at this point there's no guarantee that my Pixel phone isn't listening in all the time. That feature where your phone listens to water or an alarm is what I found too sketchy, as if they have been playing around with on-device constant sound recognition for too long and then come up with some silly reason to make you enable it.
