This thread is currently the top comment and all other comments keep lauding Bose for "doing the right thing". But actually this is a complete misunderstanding. People are reacting to the headline and the story without investigating, and have reached a false conclusion.

Bose has not open sourced anything, in any way. They re-shared a link to a years-old API documentation for the speaker itself. Their backend cloud API remains closed, and no code has been released, for backend, firmware, or mobile app. If there is a bug or security hole, it won't be patched. If AirPlay or Spotify Connect change their protocols, it won't be supported.

Literally the only change is this: "the app will update to a version that supports the functions that can operate locally without the cloud". That is to say, you can still open the app when they shut off their cloud servers, but no different functionality than if your internet was off. That's it. Even if the internet were off, you could already cast to it from AirPlay, without the app.

See other threads on this page for proof, including from some developers of alternative control apps.
