Sonos stands accused of seeking to obtain "excessive" amounts of personal data without valid consent in a complaint filed with the UK's data watchdog.

The complaint, lodged by tech lawyer George Gardiner in a personal capacity, challenges the Sonos privacy policy's compliance with the General Data Protection Regulation and the UK's implementation of that law.
