Maybe true, but I at least know in advance that these devices may be collecting data on me. I'd argue that this is mostly opt-in on my end since am fully aware of the data collection and have a rough idea of the extent this is done. Average Joe down the road doesn't give any care and still actively uses his Facebook account stands no chance against the spying. He can't see it coming.

Personally, I live a simple "non-connected" life as much as I possibly can. Any service providers I choose to entertain have to do with the minimum required information to hold the account.
