Some folks advocate for the use of the so-called Creative License except that it doesn't have beep to do with creativity:
"You are free:
* to copy, distribute, display, and perform the work
* to make derivative works
Under the following conditions:
Attribution. You must attribute the work in the manner specified by the author or licensor.
Noncommercial. You may not use this work for commercial purposes.
Share Alike. If you alter, transform, or build upon this work, you may distribute the resulting work only under a license identical to this one."
You telling me that, under the "creative" license, if I build on top of your work I have to distribute it your way????
What did you smoke last night, fella??
