Solve the issues with him and him only and leave the project alone.
EDIT:
I will try to talk to him again when he is back in the office at the end of July and try to convince him to post the pictures here. But he was really pissed about how he got treated here, so it could be mission impossible.
He gets treated exactly like he deserves. That might change if he's able to prove he's not lying but so far he hasn't shown any willingness to do so and is threatening with lawyers.
It doesn't matter that you think BitTube is the greatest project. Covering up a scam is not cool.
