at least he is not asking for a ransom
Apparently you weren't privy to the private messages.
I never wanted to get involved. I was asked to get involved in a private message by one of the developers affiliated with a prominent Cryptonote coin.
Before I went further, I stated in private messages the terms under which I would try to find an exploit. And the terms were agreed to. Dishonoring contracts is mayhem and the economy would collapse. If any parties to the contract feel after the fact that it was not a win-win, then they can in the future be aware not to enter such a contract. I entered the contract in good faith.
I am not going to respond to any more of your irrational speculation. You speak about issues of which you lack knowledge.
