OP this is not proof enough to accuse a manager of scam. Do you think building a reputation over the years is a joke for a good manager to just wake up one day and scam bounty hunters? If he had an escrow for this project payment that would have been a different case but it seems that was not the agreement and the project team are responsible for the distribution so in that case you will need to wait till December as they have said according the link you have provided up there. Then if they fail to honor their words then it is left for them.
