If you can't afford an international team of IP lawyers to actually enforce your rights, then your license really isn't anything more than a polite explanation

If you can't afford an international team of IP lawyers to actually enforce your rights, then your license really isn't anything more than a polite explanation of what people should and shouldn't do with your work. Creative Commons and its variants excel in this regard - anyone acting in good faith knows exactly what your boundaries are and they're explained clearly on the website. CERN's OHL, on the other hand, is a little bit more opaque and less well understood.
