Because at the moment most of the companies that sell online advertising monitor our "movements" on the web, Apple has included a setting in Safari that allows users to refuse to have their movements "tracked". Although some companies respect the settings in Safari, Google and other companies have chosen to ignore them, monitoring everything that users do on the Internet. Everything was discovery by a professor of the famous Stanford University who noticed that as soon as a cookie is loaded on a mobile or desktop terminal, companies can monitor any kind of traffic, on all the sites where they have public advertisements.
The scary part is that according to the researcher once the code is activated on the mobile device or the computer it allows Google to track the user across the majority of websites online. Three major online ad companies are also found to use the same technique, including Vibrant Media, Media Innovation Group, and PointRoll. I feel some serious backlash coming for Google The WSJ reports that the findings appear to contradict Google's instructions to Safari users on how to avoid being tracked. Google has since removed language in those instructions that told users that they could rely on Safari's privacy settings to avoid being tracked by Google. Google issued a statement that you can see below.
Unfortunately, today the companies that buy advertising on websites monitor absolutely everything that visitors to those websites do. This "practice" has been used in almost all countries around the world for several years and no matter how many times it is discovered, it will not be able to be stopped because the companies that sell advertising must know the habits of those who see their ads in order to deliver them. the right ads.
