Depending on who you ask cookies are either essential to the operation of the internet, or the most evil thing that has ever been created because of privacy…PRRRRIIIIIVVVVACCCCCYY…issues. This always surprises me because nobody else spends money trying to track us, thankfully all those payments on our cards or CCTV cameras aren’t keeping an eye on us. I really struggle with what the issue is here. A lot of companies and websites make their money through advertising, and better knowledge of their customers means better sales (and ads) and means they keep their marketing costs down. We live in a society which demands that the web is free (both financially and politically) yet do not want in any way to pay for it. Can you do without the internet, and you know live like they used to do in 1995?
Will I be changing my privacy settings? Unlikely. Most of the data is anonymous, and let’s be honest most of us are lackadaisical with our privacy anyway. Unless you are in living in a dictatorship there are not evil conspirators using your data for nefarious means, and if you were under one of these regimes then targeted advertisements is the least of your privacy concerns.
