Not sure if Sonos is large enough to be affected by the EU’s Digital Services Act, but I think it will be sometime next year. I am guessing this is why the change in Privacy Policy was recently done.

I would like to ask that Sonos publish all of their cloud API, not just the old version currently on their developer site. The app uses many APIs from the 1.3 API set but the docs are stuck at 1.1, missing a lot of the good stuff. More specifically this makes it much harder for third parties to integrate fully with their system, which is one of the goals of the DSA.
