It doesn't help that Dunkie was heavily secretive and public at the same time, which muddles things quite well.
Yes, he had his own Trid show and ran for President and all those other fun things. But, also, he dealt with Shadowrunners (Almost as equals in some cases! Or at least appeared to.), and had a lot of hidden goals and plans going on that make the rest of the Great Dragons look like pikers.
The fact that his Last Will and Testament can STILL be used for game ideas and concepts RL and game decades down the line is just a small piece of proof of that. And those are just the items that were for public distribution.
