OG handed over the BCH, president has been set there.
But did he
have to hand over the BCH and other "major" forks in order to fulfill the contract, or was he just a good guy for doing so?
He didn't
have to. It was obviously the morally right thing to do though.
Handing over the airdrop funds also seems like the only ethical thing to do.
OG will have less motivation to do the right thing now since his reputation will suffer whether or not he hands over the funds (unlike the BCH situation)
Hand over the air drop funds:
Confirms that he believes it's the right thing to do, also confirms that he knew it was wrong to be sneaky about it. Many will assume he only did the 'right thing' because he got caught.
Keep the airdrop funds:
He might be able to convince some people he did nothing wrong at all since it's a bit complicated. The free money isn't bad either. I think it would do considerably more damage to his reputation in the long run though.
