Personally I refuse to install corporate surveillance all over my house, but I also don't care enough to mess with custom Linux distros and arduinos and network configuration just to create a (probably really ugly) thermostat that I could control from my phone. But I would buy something like Nest off the shelf if it were privacy-friendly, and open enough that I could write some custom scripts to do neat things with it. Maybe I represent a niche market.
