So our Sonos locked us out this morning until we let it update its firmware. This is a dark UI pattern which strongly suggests they are holding the system hostage until I agree to let them remove features or add anti-features like sharing what we listen to or surveiling our home network. Anybody know of an alternative, free/open source Sonos firmware?

My Sonos desktop app made the same forced update. The “Check for Updates” dialog had a tantalizing “Later” button, but it took me back to this same useless screen.

The release notes for the update to 8.1 say only that it “delivers support for the all-new Sonos One, the smart speaker for music lovers” with a link to buy the new device.
