Buying a program half-half with a friend?

[IceAlive]

what's the point of antipiracy if more people can be exposed and benefit from a single copy of a program, like in the dorm room example above?

The way I see it is that it's like acquiring a movie and watching it with your friends. There is no piracy there.

If you want to consider the practical aspect, it's very seldom that 2 or more persons can follow the same program, according to the instructions (at least 8 hr/day, for many weeks or months in a row).
