It is too bad that it has come to this. To me, a door that cannot be unlocked if it loses internet access or that I cannot change my heating or AC, is unacceptable.

I have some privacy concerns when it comes to Nest and similar services. But in the end, this is more important. This shows that if Google decides to pull the plug on Nest, or decrease functionality (as they already did), I cannot use (a part of) the device I bought.
