A couple of caveats:
1) Yes, it was a generic name for a division of the Butokukai, but that division, in practice, consisted of Morihei Ueshiba's art. Also, the Butokukai went belly up after the war.
2) Morihei Ueshiba does appear to be the first to have adopted that name as the name of his art (Minoru Hirai opened the Korindo dojo several years later).
3) Worldwide, 99% of practitioners of "Aikido" labeled arts trace themselves back to Morihei Ueshiba. So it shouldn't be unexpected that most people regard that usage as definitive.
Chris, I agree with all your comments, those are the facts as far as I know them. I do not think they contradict the essence of my statement about the nature of the term "aikido".
