So - now we know that when Sonos was removing the ability to stream music to Sonos One and other speakers in its range from the iPhone it had this up its sleeve and said nothing. And said nothing! Frankly that's rancid behaviour Sonos. You just obsoleted four Sonos Ones in my listening estate and didn't have the courtesy, empathy or respect for my custom to tell me why. That's arrogance for you. Nor is their an upgrade path or trade-in deal. You have good listening products Sonos but your customer relations policy is bad.
