@felixbrucker, the point is not in that I can do or can't , the point is that I can MINE this coin with GPU if there is a GPU miner in exist, and so it's about the equal conditions ultimately.
well if i had a gpu miner i would keep it private, same applies here, you might not like it but it's their right, no one needs to opensource their code if they dont want to
yes that would result in no equal conditions, but so is life
