| Lack of Privacy means, no security to your data.
Let me give you a small illustration: Imagine this: you are buying a bread in the supermarket which has discount passes. That means they know what you bought. You payed with your bank card, so the bank now knows where you spent your money. Meanwhile you get gas outside of the supermarket so the bank now knows you came with the car, bought the bread and had gas. The gas station also knows which kind of gas and the fact that you decided to buy that candy-bar which was staring at you next to the counter. All bits of information which are separately not that important. But now here’s one company which allows you to say whether or not you liked the services. In return, they store every bit of information, so the bread, the candybar, the gas, all of it. And then they sell, or give away, that data to a third party.
So this tells that you data is no more secure.
This is the same scenario with the social networking sites too:
Lets consider facebook, being a prominent one;
1. One can easily have access to others profile information and get to know his connections which must be limited only to him and his self selected contacts.
2. Recently facebook started allowing people to search for updates outside facebook
3.This is a big advantage to the advertisers to advertise his products to you by collecting your information from your profile information.
Advertisers on Facebook served up 176.3 billion ads to U.S. customers in Q1, being 16.2% of the market.
I hope facebook gets this fixed as soon as possible
