Bests & Worsts Reviews from Amazon

I own three Sonos 5, six Sonos 1, and one Sonos Sub. Overall I thgink they are expensive, for what they offer, but if you have the money, and do not want to spend a lot of time setting up complicated hardware the Sonos were right for you. Good sound. Easy Interface. But the arrogance of Sonos of SOnos towards their customers is quite unique even compared to other IT companies, and is therefore ultimately leading to me selling my equipment. 1.) You will be forced to register with personal data to operate the loudspeakers, Privacy Policy (Aug / 17): "...As part of the registration, you will need to set up a Sonos account .. We collect: your name, phone number, email address, location data, your password, passwords hints and IP address" Why do you force me to give my name to use a speaker? 2.) As soon as a new firmware version is provided, you can no longer access certain menu items of the exiting firmware. The basic functions for listening to music continue to work, but certain advanced settings are no longer available until you update the fiirmware. For example, most annoyingly you can no longer add new speakers. Even advanced settings for your own local music library are no longer available. If you buy soft- or hardware, generally a company offers you not to install upgrades if you accept sticking with the current functionality. Sonos downgrades you to force you to upgrade your firmware. 3.) Now (August) a new firmwareupdate has come out. To download this, you will be forced to accept the new data protection guidelines as well. These allow Sonos to collect significantly more data than before, for example with regards to the built-in microphones, or Sonos recording what music was heard when / where / by whom. I don't want t discuss, whether the new rules are "good" or "bad", as everyone has a different opinion. But it is a fact that they are significantly different from the privacy rules when I bought my speakers just 6 months ago. And Sonos acknowledges that the Sonos speakers will ultimately cease to work if you don't accept the new privacy policy. IN SUMMARY: I understand that Google & Facebook collect data, to privide their free service. But I think, when I spend 4.000 US$ on a hifi system, I should have the right to my privacy. And even more so I should have the right to the rules not changing after my purchase. Because what's the point of any privacy policy, if the manufacturer can blackmail me into accepting whatever he wants after my purchase.
