I used to say that the only privacy protection we had online was hiding in the numbers. But no more.I think (we’re seeing) we've seen the death of privacy, with FB and Google leading the charge. What this means for our societies is unclear to me, but I don’t believe it is positive. And I choose not to be complicit.
With the massive computing power and new algorithms these days, privacy and anonymity is pretty much a thing of a past. Everything from ebooks to music to tv watching tracks us, our preferences and anything we might happen to glance at. I had a book publisher tell me that in the very near future he felt that selling reader data would be more profitable than selling books. Our cars report back to home base, credit cards and debit cards regularly track our data. Heck even your tractor is reporting back to John Deere these days. And once the bank or issuing authority starts selling or trading our "anonymous" financial statistics to other data collection firms...well... it's pretty much putting 2 and 2 together. I really don't believe anyone can escape it anymore if they use any kind of electronic transaction or service. Go ahead, wade through some Terms of Service agreements if you don't believe me :grin
But in spite of all that, I make modest use of most social media: facebook, twitter, forums, youtube, my own websites, Instagram (my favourite because its almost always positive) and let Google and Apple track me to their hearts content. Occasionally I google "how to build a bomb" just to add spice to whoever comes across my file and tries to build a profile.
