Actually, I'm pretty sure that the math on this one doesn't lie. 700 BTC > All Possible commission profit.
Then must be some reason for not releasing that has nothing to do with commission.
This is exactly what I've been saying. The only reasons, that make any sense, to turn down such an obvious route to profit would be if there were either a) more profit to be made from shady code running on the device, or b) the code running on the device is in some way illegal to use or release in the first place.
or c) He feels the IP has value outside just the amount of commission he might make, and he might want to leverage it for something else.
Just because MS isn't selling Windows XP anymore doesn't mean they're going to GPL the source if you cut them a cheque for a couple thousand bucks.
