Within a copyleft license is it possible to have a clause that would grant exclusive rights (=private license) for the same content to a company?
I mean something liky CC-BY-SA plus "company X is being given license to do ...". Is it possible to incorporate this into a single license? Or is it better to incorporate the license for the company within terms of service?
I want to cover that the company will also have "private license" to the derivatives of the content.
EDIT: Learned abozt what "exclusive" rights are and I do not want that. Otherwise the question remains the same.
