I'mma be honest. I don't understand the repulsion at the possibility of corporation X knowing my personal info, (excluding the usual things like bank account info, SSNs, etc) like my location, search history, etc. To be clear, I'm 10000000% against warrantless (FISA court "warrants" excluded) government access to this information. Here's my reasoning:
* Governments
Have the power to arrest and detain on a whim. Not to mention, use drone strikes.
* Corporations
... Don't. These entities have self-interested incentives to provide tools which are economically productive for users. For example, a smarter smartphone, whatever that may be.
Regarding Vizio, my grip is that Vizio's goal (for this product at least) is to make a profit producing TVs. So, after the TV is sold, the product is individually "finished" (not considering support stuff). So, then, what other product is the data collection for, and what does this product give me in return for my data? The answer to both is no, and not just for Vizio.
Maybe I'm naive.
