I have no interest in having a single device in my house, other than my TV, my PC, my laptop, my phone and my tablet, on the internet.
See? I already have half a dozen devices on the net, that cover all of my use cases and probably already represent a security hazard to my privacy despite my best efforts.
I don't need or want a Nest(tm) on the net that some hacker can use to turn off the heat and freeze my pipes while I'm away. The programmable thermostat I have already, with no network, is enough to set up reasonable settings for intra-day, overnight, vacation, etc. and it is secure by design. Ditto for my oven, my stove, my refrigerator, my lights, and every other fucking thing in my house.
Pretty soon a baby rattle will be networked and hackable, which will make it a surveillance, and therefor governance, device. Just the kind of world no one with an ounce of sense wants to live in.
So to those wanting to make the "Internet of Things", I would just like to say: I don't trust your security as far as I can throw it, and I won't be buying any of the malware-ridden, passively surveillant, buggy, vulnerable, finichky, and above all privacy-invading shit your selling. Move on to the next Rube, and may you meet an early and unpleasant demise.
