Can I change the name “Sage” in the theme I’m developing? and Should I keep the copyright notice intact on a theme derived from Sage?
I have no problem keeping it but do not know whether the authors wish to appear in a modification of the original theme. What is the reasonable limit to keep or change this note? Can I add my name to the authors list in my own developed sage theme?
IANAL, but I think there is a legal gap with Sage licensing. AFAIK, WP themes can be licensed as GPL or split license (as a derivative work of GPL WP).
Maybe this is not a problem for the Roots community, since, in practice, people can develop their Sage themes without problems. But doesn’t that mean that the legal stage is right. It seems that Sage try to keep away from this complex discussion.
Nothing more, just a thought about this
