Well, the fact that Microsoft does not enforce activation in Windows 10, means that fewer people need to use an insecure activator, thus making the OS safer for more people, even people who do not plan to pay for Windows. By making the whole OS free, MS needs to get their income from somewhere else (spyware/ advertisements?)

They are getting money from license, believe me. Big company pay to get license for Windows and other programs for example WinRAR.
