I'm not sure I like either of these -- I find them more confusing than just "The license may require derived works be licensed in a particular way, as long as derived works can still be distributed under these guidelines", and I'm not really sure what we're trying to avoid here. There are a few cases worth thinking about: * The GPL requires all future versions to be distributed under the GPL, essentially. This is okay, because you can require the same license, essentially. * Modifications released under the QPL 0.92 are available to anyone under the terms of the QPL, and to Troll under terms "You can do whatever you want with this, as long as you release new software that incorporates it under the QPL as well as however else". But this seems to come under the "release under the same license" clause anyway. The current DFSG says "You've got to be allowed to release modifications under the original license". Perhaps we should just leave it like that, with the justification that ``just as free software programmers shouldn't have to be rich to be able to contribute to your code base, they shouldn't have to be lawyers either. A simple license is a good one.'' Are there any licenses that can't just say ``if you make some modifications, just leave the license as is. if you _really_ care, you can also do such-and-such...'' ?
