A building/house is a patchwork of different technology too, but it's useful sometimes no ?
Moreover, two distinct builders use cement and bricks, does it mean that their constructions are the same ?
Oh, I was not expecting someone with a brain here.
Well I reply in this case...
I was pointing at the open source problem. Anyone can copy open-source tech, that's why there is so many altcoins. There are based on Bitcoin.
Sometimes, an altcoin bring something new to the table or at least improve something. Because the altcoin devs used open-source technology from others, they provide their code in return.
Until now, Darkcoin hijacked this circle by not giving back. That explain why some people ask for it.
I was just looking around while I saw the user guanchayuan asking for open source. Everyone got mad and insulted him. I decided to react despite I knew that I was going to be insulted for saying the truth.
