What's different from this "version" than what you've heard elsewhere?
I've searched and found no mentions of NDAs/non-competes. The only contract ever mentioned is an oral contract, which means they told him the idea, and then I he agreed to work on it. In addition, Zuck's subsequent deceiving emails to ConnectU are well-documented.
My point is not to challenge the facts about what occurred and when. My point is that the concept of "oral contract" is hugely vague: clearly Zuckerberg didn't believe he had a legal obligation to complete their website. And in this case, the ramifications ($65 million) of breaking such a vague agreement were much too high.
Your interpretation is not the only possible one, and fails to consider the significance of the fraud involved. If it was a story of two business guys who stole a pile of code and built a business I suspect you'd be demanding jail time.
