CDDL wasn’t created by radical leftists, nor has anyone ever been threatened with a lawsuit for using it either. GPL was created by radical leftists, and they are proactively looking for others they can threaten of course as well.
Give it time eventually uoull see the CDDL licnse cause some trouble.
“The CDDL clause on forcing an entity to stop using CDDL software in case the company sues for patent infringement is, in my opinion, a gross poison pill, onerous to the small company whose patents are being infringed upon. You and I may not agree that patents on software should even exist, but the reality is that they do, and are an important asset in today’s world. Forcing a company not to use the CDDL in the event such company wants to sue to protect its right is, in my humble opinion, worse of an infringement on freedom than any of the GPL2’s terms.”
In other words if I use the CDDL and suddenly I find SUN infringing on one of my patents I cant sue them unless I stop using the CDDL.

And here we prove that your problem isn't with the provision of the license itself, but with the person who wrote it.

A copyright holder who doesn't proactively defend his copyright might as well not have it.
