I'm more than a little concerned that this is not the default answer to this question. While Nest certainly shared blame in choosing FB as their partner in advertising, I think the real problem is the FB only cares about advertising.

I'm amazed at the number of people that I hear complain about this stuff and yet keep using FB as if it is essential. For instance, add your cell # to your account to confirm developer status and then turn off notices. You will still receive texts from FB because they don't give a damn.

For the life of me, why people willingly give so much of their information to a company who clearly does not care about privacy is beyond me.
