A question about piracy.

We all know that software piracy is wrong right ?

We also know that Bill Gates robbed his Windows software from Apple.

Analyzing more in a ethical way than in a legal perspective. Would we be doing piracy when buying the original Windows software from Microsoft ?

Well considering many people do piracy then i would say i dont know.

Haha. That's like asking, are we all "pirates" because it is human nature to destroy the planet and other sentient life?
