I'm not the dev, I'm the community manager. The xc source code is not being open sourced for a long time as in years, we don't want clones of xc and people have asked for it not to be open sourced.
Sorry I thought you are Dan, the main dev.
We have just seen design of
http://www.xc-official.com/and we are afraid XC source is the same by design.
Also we afraid, whether in critical situation, Dan can easily embed backdoor into XC under a FBI pressure. He is a good man, but he is just a good man with family and children...
So for years, as you mentioned, nobody guarantees our own anonymity.
You could say backdoor could be embedded into every computer. So what should you do? fuck your computer? Just remind you, turn off your computer before fucking it and add some lubricating oil at CPU socket. Have your good time.
