The whole "copy protection" story makes no sense. they screwed up and don't want to own it.
Now I'm puzzled. Perhaps I don't have enough technical knowledge, but what makes you think that? I'm not a fan of Iota at all, I think it is so centralized to be practically almost a scam, but in this specific case, what makes you think they are lying?
They put a non tested and easily breakable hash function in their code, jeopardizing their whole project. MIT could have simply wiped the whole project out, but they chose to be responsible - and look how the iota team treated them.
Who would "copy protect" their code by breaking their production cryptosystem and distributing it? The very idea is so absurd it's inconceivable.
