There are rules in the D20Stl for using D20 within text-based products. It includes the text that must be used. If, on the other hand, you believe that it is alright to use the term "D20" however you wish in reference to a gaming system that is entirely your right to interpret it as such. However, I would recommend consulting legal council before publically declaring any such interpretation. I, certainly, do not believe that the team at PCGen intended such "nitpicking" of the license as to imply the use of the term "D20" which does not fall under any fair-use provision that I'm aware of, and I believe it's unfortunate that people would put words in their mouths that might be taken as a legal standpoint.
No offense, but have you actually read the d20STL and the license guide? "D20" and "d20" are not in the list of trademarks. The list of trademarks governed by those licenses are (quoted from the guide, with my parenthetical explanation of the first item):
The d20 system logo (the stylized graphic image)
The trademark "D20 System"
Dungeons and Dragons
The Dungeons and Dragons logo
Wizards of the Coast
The exact word "D20" is not a trademark. It's not even trademarkable. It's a) a noun which is not distinguished from its common use as a noun, and b) it is, and has been, in common use since before anyone thought to try to trademark it.
"D20 System" works as a trademark because D20 is not being used as a noun, it's being used as an adjective which modifies/specifies which "System".
Remember, we are talking about an application that is designed to improve gaming and to make everyone have a more enjoyable time playing a game - not one where the designers set out to nitpick and try to personally find a loophole in the d20 license that might, in fact, hinder it. I believe it's in all of our best interest to help them as we can, by being constructive, not to try and find loopholes that they can slip-through.
It's not a matter of legal loopholes and nitpicking. It's simple truth that "d20" and "D20" are not trademarked and not trademarkable, and thus "A D20 Character Generator" is not violating anyone's trademarks.
Further, it's not a matter of creating legal loop holes to try to figure out a way to indicate something without using its trademarks. I want to indicate that I'm a program that works with the d20SRD, so I think of a way to indicate that which does not violate trademarks. I notice that "d20" and "D20" are not trademarked, so I use them. (personally, I prefer to actually say "d20SRD" instead of just "d20")
Saying that that's nitpicking and loop-holing is like saying that knocking on someone's door and asking to come in, instead of breaking in a window and crawling through, is nitpicking and loop-holing. I want access to someone's house so I ask my self "what's the legal way to do that?" and go follow that track.
Similarly, I want to indicate association with the d20SRD (but perhaps not with particular d20 products), and I want to do so in way that doesn't violate (nor use) the d20STL. So I figure out how to do that, which means I use non-trademarked terms, like "d20", "D20" and "d20SRD" (though my use of D20 may not include "D20 System"). It's not a loop-hole in any way.
