Re-read their "open license". It is retaining the IP to no one but themselves.
Is this Bad or Good? I'm really not sure @im_uname. As I understand it, the IP is free to use for any developers in the Bitcoin Cash blockchain. Does nChain have an endGame?
"Just like Microsoft's Limited Public License has a platform limitation for free usage, nChain's license limits free usage to the Bitcoin Cash blockchain." https://prn.to/2qBCqxM
It is not free for any developers on BCH. It is free for developers who ask and get permission - big difference. Actually read the damn license, not just PR release.
