Microsoft would never kill off Piracy.
They became what they are because of Piracy. It's so obvious. They know the best way to become the dominant player is to flood the market with their software and make it easy to get. They knew a lot of their home market could not afford to shell out the money for a windows OS. Make it easily accessible then when 95% percent of the market has Windows on their computer they can recoup their losses from Piracy by charging the wealthy (companies) insane licensing fees. MS knows there is no money in the home market. But what better way to get the OS in businesses than to get installed on their machines at home. People will get comfortable using it at home and will want the same at work.
Piracy did not kill the Amiga either. In fact in sold more amiga machines. That's a fact.
