Collabora Online 1.0 Engine License

[Adam Saunders]

Hi all,

I understand that the Collabora Online Development Edition (CODE) is 
fully free-and-open-source, but what about the "production-grade" 
version, Collabora Online 1.0 "Engine" that was just recently released 
(https://www.collaboraoffice.com/press-releases/collabora-productivity-releases-collabora-online-cool-1-0-engine-for-hosters-and-clouds/#comment-17242)? 
I ask because CODE contains, in part, permissively-licensed source code.

Thanks!
Adam
