Hallo, Hans-Christoph Steiner hat gesagt: // Hans-Christoph Steiner wrote:
My one issue is how to prevent unscrupulous use of work that is released freely.
You know this: The catch in the GPL to prevent unscrupulous use is, that all derived works have to be GPL again (the "Share Alike" in some CC licenses). So even if someone takes your work and builds upon it (which is something you probably want to encourage), it will flow back into the free code or art world.
If you want attribution as well, there are ways to ensure this, in the CC Attribution license this is made very clear, but I guess, this is possible with GPL'd work as well.
