That is correct.

Yes.

That's also correct. The problem is, then the issue becomes having an 
independent expert witness go through the allegedly infringing code line 
by line and deliver an opinion on whether it infringes or not, and if 
the judge & jury buy one side's expert witness or the other side's. Even 
if you win, there's the lingering bad reputation. (Ask anyone who's been 
acquitted at trial.) Boo on that.

Having some taint and lingering suspicions of infringement for hobby 
software is not a big issue, but for software to be accepted for 
professional use, professionals absolutely will not take the risk of 
betting their companies and reputations on software with an iffy legal 
status. D and Phobos must be absolutely clean in this regard.

For a notorious example of the trouble this kind of thing can cause, 
just look at the ongoing Linux vs SCO wars in court.

I'm very sorry that SHOO got caught in the gears of this licensing 
issue. I apologize to him, and I sincerely hope this experience will not 
dissuade him from continuing to contribute to D.
