I would not at all be surprised if they are listening. But isn't a simpler explanation that your in-law was googling driveway options, clicked through a link to see what the heck airport grad tar even is, and then google saw you were in the same vicinity and guessed you'd have similar interests? I wonder how many other ads you had in common that week, or if he saw ads for the underwater basket weaving course you purchased, etc.

That still raises the question of HOW because I never used their Wi-Fi neither has my wife. So Nest uniquely identified my voice, captured the conversation and told Facebook I must want airport grade tar?
