Because there's an astounding amount of data leakage from something like this. For instance: Network snooping / spoofing / etc (even if it's on a VPN through an external router it still leaks congestion information!), temperature settings, especially versus actual temperature, power fluctuations, vibration sensors, etc, etc. I don't particularly want random people knowing - and potentially selling - information about when I sleep, when I eat, when I take a shower, when I'm not home, when I'm on vacation, etc, etc.
