Well, the most obvious explanation is that Zuckerberg had lost the paperwork pertaining to a short and unimportant job, maybe ten or twenty hours at an economic rate.

Young men are often not careful about that kind of thing. The job would probably have involved integrating publicly available open source code into a system in which Ceglia would have had severely limited exclusive rights. That is the kind of thing you can do in ten hours.

It seems doubtful, based on available evidence, that Ceglia was honest at any point in his life, but if one assumes the motives of an honest man, the idea would presumably have been to get some kind of quick-and-dirty version of his street-view-type system going, so that customers could start using it. If the business proved viable, it would later have been feasible to do a better job and port the data over.

Given, of course, what we know about Ceglia, that he repeatedly sold things he did not own, the indication is that he was probably trying to “sell the Brooklyn Bridge.” That is, he wanted Zuckerberg to spend ten hours tying together open source code representing tens of thousands of hours of work, much of which might have been protected by the GPL or some other restrictive open-source license. Ceglia would have had every right to run this combined system on his own website, but he might well have had the bright idea of selling “exclusive rights” in the underlying code to gullible investors, just as he sold non-existent firewood, and real-estate which belonged to someone else. This would explain why he might have drafted a contract to give the impression of more activity on Zuckerberg’s part than was actually the case.

So we are meant to believe a billion dollar company who produce a badly blurred digitalised contract over one man who produces an original paper contract which has being forensically tested and verified? think about it why would Facebook take this case so seriously if it is one big fraud? surely facebook has the funds to hire lawyers capable of killing of a fraud in minutes. The only explanation can be that Ceglia has a solid case and when you view his evidence this is found to be true. And how the judge has acted reminds me of how the judge has acted in the Strauss Kahn rape case, As soon as the innocent room attendant has tiny flaws in her argument the judge throws the case out. Why ? because power protects powerful people ! and this is the case in the facebook-v-Ceglia case.. like come on do people really think Ceglia is that stupid to take on Facebook in the courts if he has no legit evidence ? the man has ran companys in the past he is intelligent enough not to try and fraud facebook .
