This is beyond annoying. Now I have to decide whether to simply stick with the stuff until none of it works anymore, or support @sonos and it’s crappy bricking strategy by throwing even more money at them

Isn’t this every piece of hardware that has turned to software driven products? Even car head units that drive your GPS and radio have an end of life for something you paid $20,000-$100,000 for. I know a friend that can’t listen to the radio in their car anymore.
