Maybe. I’d say it’s more corporate for Sonos to try to develop yet another closed wireless audio sync protocol just to force users to sign in through their app so they can data scrape you. In the absence of a true open wireless sync protocol (maybe there is one and I’m unaware, in which case I’d like to be educated!) I’d rather them use a more widely adopted protocol than roll their own.

Edit: I think maybe I misunderstood the comment I replied to and they were agreeing with this statement in general.

Sonos actually uses AirPlay as well. Frankly, they lose when it comes to multiroom audio vs that interface, and they need to make their money off of selling speakers (compatible with AirPlay and other services). Their problem is they wanted to be a clearing house of users listening habits, where you’d need to use the app for them to track that (where you sign up / in with your services); that’s asinine, and they just need to be a speaker company.
