This is silly, no one is saying they are going to brick the hardware, ever. But if you don't update and years later Spotify decides to change their end points, Spotify will likely stop working on your very outdated speaker. If you have any google account or android device, they already have literally orders of magnitude more info on your life than Sonos would ever be able to collect. Not to mention Sonos has said it doesn't ever sell the data, AND you can opt out of usage info. Not seeing the problem here.
