Google also hasn't done itself any favors with its clumsy, teenaged-boy-trying-to-get-to-second-base method of pushing Google+ at every opportunity. Just last week, Google announced that your Google+ contacts would be able to email you, even if they didn't know your address, a feature that seems like it will invite abuse by spammers, marketers, and other people of dubious intent. Yes, you can disable that feature — I'll pause while you do exactly that — but Google has put the onus squarely on you. No, I don't seriously think Google's going to cut off the heat of Nest Thermostat users who don't embrace Google+, but I wouldn't put it past a company that ham-fisted to use your data in a way you might not approve of. "Hey, this guy seems awfully chilly," Google might say to an apparel advertiser. "Why don't you send him an email asking if he wants to buy a sweater?"
Look, I'm not entirely naive here. I type something into a search engine, I know that my keystrokes are being recorded somewhere for purposes other than returning results for the information I seek. That's the concession you make when you use services of that ilk, and if you don't like it, well, your local library contains plenty of wonderful encyclopedias and atlases. Inviting Google into my home, whether it's to turn on the thermostat, the lights, or anything else, is another matter altogether. Your home is your castle, the one place in a weary world where you should be able to duck out of view for a bit from persistently prying eyes. Any connected device is going to impinge on that, so I'm especially cautious about loosening my grip on the privacy of my home. Once even a little of that is given away, it's really hard to get it back.
After all, it ultimately comes down to trust. I only like inviting guests into my home that I can trust. And Google hasn't earned that trust, no matter what its vision for the automated home may be.
