Under those circumstances, enforcing copyright law against individual users is very nearly impossible. If my university decides to save on its software budget by buying one copy of Microsoft Office and making lots of copies, a discontented employee with Bill Gates' email address could get us in a lot of trouble. But if I choose to provide copies to my wife and children–which under Microsoft's license I am not permitted to do–or even to a dozen of my friends, there is in practice little that Microsoft can do about it.[5]
