Interesting and scary. It is true that many don't understand what extent they are followed, but I wouldn't call it spying. The truth is people overshare, but only because they don't understand the consequences. Imagine that you have that person who follows you home, but instead of making them stop, you tell them your life story.

Thanks for your comment, I agree with you people share too much information about them because they don't realize the consequences but GAFAM also steal our personal data, actually it's not spying because it's marked in the terms of use but who reads it ?
