Future analysis anyone?
Does anyone else think future sound analysis system seem to be the obvious reason for keeping search recordings?
All those lovely background sounds revealing lots more about you and what's happening when you order. Currently they only have 'assumed' search requests heading home, they'll be keeping the 'Oops we accidentally left permanently recording everything switched on (for testing) after the firmware update' excuse for future use.
GDPR violation excuse - 'We need the recording for training purposes' (billions of them)
