I'm so confused by some of the stuff in this thread. I still use my sonos stuff and never even noticed the update beyond seeing that the UI changed a little at some point. I know people had some issues but I never stopped being able to do what I wanted with my beam, sub and a couple of satellite speakers in other rooms.
I use streaming services for music when i'm not using it for the TV too. I usually use the streaming apps themselves rather than the sonos app to do anything. I have set some custom EQ stuff with their app, but that's understandable.
I don't think they are anything special and they are very expensive things for what they do, but my problems are very few and far between. Every now and then my beam doesn't get commands from HDMI via my TV... and the TV is always the issue (it's old.) That's really it. I'm not in love with the stuff and when it's time to replace it i'll look at what else is out there, but I don't hate it either.
