A quick summary of The Decoupling Principle: Separate WHO you are from WHAT you do

An example is Apple's iCloud relay. When you browse a URL, it is encrypted and sent to the first server, owned by Apple. This knows WHO you are, but not what you are browsing. The Apple server then sends your request to the second server, operated by a third party such as Fastly. This server gets to see your URL, but it only has Apple's IP address, so it knows WHAT is being browsed, but not WHO you are.
