Assuming Jeremy's story is true, then by the time he exercised that strategy he'd already by forced out by his co-founder and was no longer a "teammate".
I don't think it's fair to judge the ethics of a person by how nicely they respond to being screwed over.
So is cutting someone out of a company. My point is that this probably became an emotional issue. If that's the case, it's not hard to see how someone would wait for an opportune moment to assert ownership.
But, since we don't really know all the facts, if this was a mutual parting of ways, then I agree that it's a terrible thing to do.
The bottom line is we really don't know what happened. I can at least see how a reasonable person could walk this path if they feel they've been maligned.
...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.
