The blog post, written by product management director David Baser, is mainly about third-party websites and apps that send data about their users to Facebook, regardless of whether those users have Facebook profiles.
There are, however, other companies too that offer these types of services and get information from the apps and sites that use them.
Mark Zuckerberg also said in a press release, and during interviews that all of Facebook's 2 billion users could have had personal information and online information used improperly and against company policy, but maintains that he is the best option the company has for a CEO. Facebook, which was developed by Zuckerberg in his college dorm room, has revolutionized how people connect with one another. "These companies and many others also offer advertising services", adds Baser.
As it turns out, Facebook, which is in the business of gathering as much data from as many people as possible in order to run precisely targeted ads, gets its information about you from many sources, not just what's on the profiles of its users. It includes cookies, IP address and browser info from other websites. However, if the website you are visiting uses Facebook technology, you are often left with little choice. "Facebook doesn't sell data".
Facebook's request asks users to review their Messenger privacy settings by May 25 - which happens to be the same date a strict new European law called General Data Protection Regulation (GDPR) begins. He wrote Twitter, Pinterest and LinkedIn use similar like and share buttons like Facebook do to help people share various things on these services.
Google has its own Analytics service.
Facebook also committed to making it easier for users to access the data shared with the platform by downloading a secure copy and moving it to another service. Let's hope the company eventually makes it possible for non-users to see and delete data that Facebook has collected on them.
But he went on to stress that the practice was widespread by citing the example of other internet giants like Google and Twitter for doing the same.
Switching it off will mean that you don't see ads "personalised" to you on other sites.
For example, a few years back Facebook opened the accounts of nearly 600,000 members to manipulation to find out how easily one could change the feelings of uses of Facebook, this was part and parcel of the Central Intelligence Agency activity.
