Which anyone can do when combining CC-By and CC-By-SA works by others.

I can't combine the NC-SA and SA works of third parties without negotiating alternative license terms; the licenses are mutually incompatible. The limitation of BY-SA keeps the work and it's derivatives freely licensed. True— it's a limitation, but it's one that merely contravenes some of frequently anti-cooperative aspect of copyright protection. You can look at SA works as existing in a parallel copyright universe where restrictive copyright controls do not exist. This is categorically different from the (often vague) nature of use restrictions connected with non-commercial licensing. _______________________________________________ foundation-l mailing list [email protected] Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/foundation-l
