Sonos, the current popular brand of smart speaker that people don’t [yet] talk to, really wants its customers to agree to the company’s new privacy policy; so much so, that failing to acknowledge the new rules can turn your Sonos speakers into very expensive shelf decorations when they eventually “cease to function.”

Yes, that’s the problem with “smart” devices. They depend on cloud-based software, which means that when the company that operates its software goes out of business or decides to make the device obsolete, certain features or the whole device will no longer work.
