I haven't seen the evidence, but it seems to me to accuse him of code theft because the moves end up being the same seems a bit much.

Did he refuse to show his source code?

Also, claiming that he knew he was in the wrong because he denies being in the wrong is too much, too. He's more guilty because he claims to be innocent? Jeez.

Also, demanding the trophies and prize money back is fine, but if they take him to court over them, that's going too far. He might very well not have the money any more. That it took them 6 years to figure out he was cheating says it wasn't very obvious, to me. And now they claim that there is overwhelming evidence.

I dunno, something smells fishy to me. I'd certainly want more proof than 'it does the same moves'.
