The only thing we can speculate about is what we would have done in his shoes, unless he provides a convincing insight. If it was me, and I cared about a project of mine for the sake of the project and thought it was a vital project (as opposed to one of my tinker toys), I would have open sources the whole thing, no dual license. That way nobody can "steal" it from the community, by buying some company. I would also have tried to give it to someone like the Apache Foundation, so that when I die, my project does not.

On the other hand, if I thought my project was going to be a cash cow, I would have done exactly what Monty did, except the whining after the fact. I think if I buy a car, then sell it to someone and that person sells it later to my arch nemesis for a discount and he plans on wrecking the heck out of it, my screaming about how this is not right is not going to attract many supporters, is it?
