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.
