I've stopped buying devices that require some nebulous "cloud connectivity" to function. It's no longer an exchange of value that benefits me. My personal data is valuable and I see no reason to just hand it over to companies for no compensation. That's what you're doing when you use one of these cloud connected devices. You're giving up real value to gain nebulous value. At least that's how I see it--you might disagree and that's OK.

Particularly annoying are those devices that should be able to function without phoning home via an internet connection:

Security camera? Shouldn't need to phone home. Camera should turn on and stream directly to my display device. There's no need to connect to the mothership.

Thermostat? Shouldn't need to phone home. Device should let me control the temperature of my home and respond when I command it remotely. No need to connect to the mothership.

Media player? Shouldn't need to phone home. I have a library of files I'd like to play and don't care for any online services. No need to connect to the mothership.

I used to have a rule: If I don't have root on the device it goes on the guest network (no internal network access, only Internet). I still have that rule, but it's time to up the rule to "no internal or external network access without root".
