To me it seems that like with any contract, the money is his once he fulfilled his part of the deal (ad views/clicks). I agree that not payout out is not the same as stealing, but in this case it does seem awfully close since Facebook is acting as a middle man. If someone hires me to do a job for a 3rd party, gets paid for my work, but doesn't pass me my part - I'd call this stealing.

But if it was determined that the part you did was done fraudulently? That's essentially FB's position here. And their contract states that the remedy for that is account termination and forfeiture of the balance.
