I can't stand moguls, raised by hippies, so I rather lose 1%, than support a selfish person 2%
But hey if there is another dual miner that would be great.
There's no other dual miner so that's why people pay the 2%. The additional profits offset the dev fee for those inclined to do so. Supply/Demand. Why would someone make a dual miner and share it for next to nothing? They'd probably keep it to themselves to improve their own hashrate.
