...Because you have an agreement with someone that you were a 50/50 co-founder, and that agreement is on paper? Sorry, are you privy to some kind of proof that invalidates Guillory's central evidentiary claim -- in the same way that Zuckerburg and Facebook were able to show that Paul Ceglia fabricated a contract -- or are you just arguing from circular reasoning that Guillory is a greedy asshole and thus his claims that he was unjustly forced out must, QED, be false?
I think the claim is that demanding what is rightfully yours is greedy and selfish. I don't know whether I agree in this case (probably not), but there have been cases in my life where I do agree.
It's that "rightfully yours" bit that really bothers me. Where does that come from and why is it so obviously rightfully yours? It takes some gumption to assume you're in the right. This land is rightfully mine because I bought it from someone else who genocided a people, but okay great, it's rightfully mine, I feel super great about it.
Legal documents are part of a negotiation, not a casual conversation. If one side says they owe you nothing, you come in saying they owe you everything. You meet in the middle.
