There was another paranoid post recently on this topic, with a reply from a Sonos staff member explaining why they need location details for legal reasons, and the limited use they make of the data. 

In fact, I now note that you’ve seen that thread and added your paranoid comments on that thread too, despite Sonos’ comments on their use of the data. 

i would not call myself paranoid, more like a privacy conscious citizen. glad someone reads my posts.
