Hello there Tarus,
Respectfully got to disagree here,
CopperheadOS is not "source available", as their lead developer explains above.
I've got to respectfully disagree with posting this article on opensource.com.
Copperhead OS is not open-source, since it does not permit commercial distribution, its userspace components being licensed under CC-NC-SA, which is neither an open source or free software license.
It's a great project, but it's important to be correct when talking about it.
All the best,
