I'm sorry if my post came across like I worship at the altar of google. I personally use AdBlock and noscript, so I haven't had to deal with ads in a long time.
Advertising and data collection are a huge business, and Google is not alone in exploiting this trend.
Even if you do use one of the numerous search engines or web services that claim to protect your privacy, there is nothing from stopping them from selling info down the road.
The point I was trying to make is that using the internet in and of itself means you will be tracked and exploited for profit by some company. Surveillance cameras are everywhere and will only continue to come into service, so the notion of living a private life and being a normal member of society are coming to odds more and more.
I can tell you one difference between Google and Facebook as far as how they spend their ill-gotten gains: Google is at least using it's investment capital to acquire companies that are geared more towards advancing technology, such as Boston Dynamics, and their autonomous automobile projects.
I personally have no problem with your thread and agree that "big data" is a topic that needs to be discussed. I think Google and Facebook both are very overvalued companies. Acxiom is probably a bit more realistic when their main source of income is a consumer feedlot.
I was replying to Red Squirrel because he, again, misses the bigger picture when saying people should just host their own email when it is way beyond the technical expertise of most email users. Since most people don't thoroughly read EULAs, even the so called "privacy pioneer" alternatives can easily wiggle out of selling data and hope it doesn't get a lot of attention.
