Thanks for that bit of background. That make sense.
I used to think that MS were probably happy with a certain amount of “piracy” (students, voluntary groups, people starting off as self-employed contractors, etc.) because it kept people in their ecosystem (using MS Office and other Windows-only software), helped reinforce the perception of Windows as being the OS for getting stuff done (either work or games) and some of these “pirates” would become future (paying) customers.
