Hey, maybe you're on to something... I'm beginning to understand now why Google paid $2 billion for Nest. Previously, I saw that as a couple of rich guys indulging themselves with stockholder's money (which is also partly their own - then again, Larry and Sergei have more to spare Google's other stockholders.) It makes a lot more sense, though, when you throw in the whole tinfoil hat thing: presumably, the Government (read: NSA) wants to know what temperature people find to be "comfortable" in their living rooms - and maybe even torture terrorist with the wrong setting, now that waterboarding has been discredited. And of course that's only the start: if the whole "IoT" thing really takes off, Google's (subsidized) Nest thermostat will be asking our refrigerators whether you and I need to buy another gallon of milk - and I say it's none of their darn business!
There's probably also a good tinfoil-hat reason that Microsoft paid so much for Nokia's money-losing phone division. I can't see any advantage for the Government (read: NSA) to subsidize that, but it just proves them Feds is a whole lot smarter than I am. And don't even get me started on NSA's nefarious plans for Minecraft...
