Yes, they do.

Maybe not gschem, because it doesn't push the state of the art, 
but there are known issues with gnucap.  Icarus is vulnerable 
too.  PCB, probably not yet, but if that new autorouter is any 
good....

You do something that somebody else decides to patent.

Somebody else builds on your work, and gets a patent based on 
their enhancements, something you had already planned to do but 
didn't yet because of a lack of time.

This has actually happened, in EDA.

"More likely" means "nearly 100% probability".

The changes in GPLv3 are the result of actual issues.
