Since most map authors don't provide a license with their maps, you have to assume they are copyright by the author and you cannot republish those maps (modified or not) without that author's permission. If we wanted to we could force map authors to agree to make their maps open source when they are added to the Remake (agree to some kind of license), but for now we don't get map authors to agree to anything at all.
Personally I like open source and allowing others to improve/modify/hack your work, as long as they give you attribution. Hence all the 100k lines of code Krom and I have written for the KaM Remake is open source and anybody is free to use that code in their own projects, or modify the KaM Remake and redistribute it (once again as long as it is attributed properly), regardless of whether their changes can be considered "progress" or if they made stupid changes we don't like. KaM Remake has benefited from other open source projects, for example PascalScript which we use for dynamic mission scripts (we would never have written something that powerful ourselves just for KaM Remake).
But I'm talking about code not maps. Perhaps maps are more like works of art than code. Sharing/copying code has obvious advantages, but it doesn't really make sense with artwork. Similarly players wouldn't like it if most maps contained bits copied directly from others (or if most maps were just slightly modified versions of old maps).
Regardless, map authors put huge amounts of time into their maps and are entitled to license them whatever way they want. Krom and I can set rules about what map licenses we accept for maps included in official releases, but so far we haven't.
