In the case of Squeezebox, Logitech stopped selling them a while back, but to their credit they are still actively maintaining the self hosted server: https://github.com/Logitech/slimserver which has some plugins and bridges to other services.

I would say what they are doing with Squeezebox is the best case scenario for a lot of these connected devices, even though the complexity of having a self-hosted option is in no doubt part of what lead to their failure.
