"I just bought into the Nest system (which also had great deals on black friday), and I'm just not worried about it.

You need to be doing everything you can to discourage any sort of data in this data-economy-style world we are pushing ourselves into. And if I want to walk down the street, I sure as hell don't want your camera recording me, especially since knowing the involved company, one way or another that recording WILL get used for a monetary purpose, and I sure as hell didn't sign a model contract, so despite being in public you're still potentially violating some of my rights with your doorbell camera.
