we do know for sure there was 3miilion shorted on bitfinex just prior to DAO attack ...a huge interest by any measure. Coincidence, I think not. selfjustice is how the system is designed isn't it. Miners ultimately choose whats in their best interest....its the cornerstone of having a distributed pow blockchain. And if they choose to mead out justice in the form of a HF than so be it. Those who don't like it can rent or buy mining equipment and hash another fork.
I will support the hard fork with my GPU mining power. Although it is small hashing rate, it is my contribution to the network.
