You can play stuff you physically own from a Roku too. Are you saying that Sonos could arbitrarily upload your media files to their servers? Doubtful. At worst, they could do a sound-print analysis locally on the device to identify it and send the metadata to Sonos.

I am trying to think of concrete examples of scenarios where actual harm would REALISTICALLY be done to individual consumers because of Sonos privacy policy.

1. Government 'dissident' listens to 'subversive' podcasts via Sonos.

2. Government compels Sonos to provide data on customers' listening histories.

3. Chilling effect, political implications, oppression.

If you're a "government dissident" and you're inviting internet connected always-on microphones into your home - you're doing it wrong...

"Alexa? Send details of my subversive plan to the government!"

"OK Google, upload the audio of the last 30mins discussion with my co-conspirators directly to PRISM!"

"Hey Siri? Which law enforcement agency needs to know about this surprise protest we just planned?"

What does this have to do with Sonos?

If an out-of-control oppressive government is the real concern here, is a flimsy EULA _really_ going to provide any protection whatsoever? Can you really even have 100% trust that the EULA will be obeyed by the company if they can get away with violating it?

I'm not pleased at this Sonos development either, but that's way too tinfoil hat for me.
