If this surprises you, you must not understand Google's business model at all. They give you services for "free" (or cheap) so they can use your data for marketing analysis. The thermostat tells Google when you're home and when you're not, tells them when you go to bed and when you wake up. Tells them when you go on vacation, and with the Nest Mobile App, where you went for vacation. Tells them how frugal you are with energy. This is a lot of valuable data to a marketing company, so of course they aren't going to lock themselves out of it.
