“The most important thing for you to know is that Sonos does not keep recordings of your voice data. It goes to the voice assistant service (for example Amazon) that you’ve activated on your Sonos system."
Would this mean that Sonos will be using their own embedded microphones to essentially turn the speaker into an Alexa device?!

EDIT: Ok, according to this, Sonos will release speakers with Alexa embedded in them. I wonder if older speakers get to spread the joy…
