I saw the Facebook movie yesterday, and I was discussing with my girlfriend whether Mark Zuckerberg is really at fault when stealing the idea, as shown in the movie. We decided, "not really".
I mean, suppose I have an idea, and discuss it with you, but don't do anything about it. You go on and develop my idea into a product that you sell to others. Do you have to compensate me? If so, a lot of businessmen would have to compensate others. Most products (I would say 99.99%) are copied from others in one way or another. i.e. someone comes up with a new product (e.g. a watch), and other copy the essential idea, change the design, and sell it.
Although I agree that if I paid you to do something, and you did this but lauched the product yourself, then you might be acting illegally. Though in the movie it said that Zuckerberg didn't use any code of the other folks. He wrote them all himself.
So, what do you think? Is Zuckerberg in the wrong or not?
