The proposed change would mean all works where the "country of origin" (as legally defined by US statutes) is a non-treaty state would be declared as public domain for the purpose of Wikipedia and allowed to be freely used. The current discussion features a 9-3 "consensus" in favor of this outcome [2], and some participants are now pushing for implementation on this basis [3].
If U.S. law (or rather lack thereof) is to prevail because the projects are hosted in the U.S. I have two questions:
1) How would re-use of Wikipedia content look like to users in the respective countries? Wouldn't they be limited in re-using some content if it was obtained from sources under some kind of protection in their countries, but considered public domain in the U.S.?
2) What about projects like Farsi Wikipedia, where we can assume significant amount of editors comes from Iran - are they legally able to license that content to the rest of the world?
