Which sector is building startup after startup for data mining, tracking, building profiles? This in addition to the already established companies. Then you're trying to downplay the issue to trivial actions such Facebook likes or tracking of IP addresses, a toy version of the state of the art. Finally, the sarcasm, showing how reasonable you are and putting the OP in a bad light for not being "more understanding".
It's quite simple: the topic of privacy is central to a free society and it's enshrined in the Universal Declaration of Human Rights. In the past, we have seen a rich history of abuses, lies and deceit from huge organizations with massive resources at their disposal. Private or not.
The majority of people go on with their lives without caring, as long as they have their basic needs met. The very few that take a stand, pay the price. Otherwise, some criticism of the behavior of these organizations can be found online, but not much because of:
1) Chilling effects. Funny how I had to think before posting this message, living comfortably in a democratic country, with freedom of thought and freedom of speech.
2) "Helpful people", quick to jump to the defense of said organizations, explaining away abuses, making up excuses, muddying the waters, asking for fairness and understanding their point of view.
So thanks for keeping the balance karmacondon. They might have mountains of money, lawyers, shills, PR people and most resources imaginable really, BUT we wouldn't want to unfairly hurt their feelings. I do apologize for that.
