Hmm, not really sure why this one has been resurrected, but as it has, some corrections....
Honestly, most of what you've put here is incorrect. Hatsumi was always teaching a variety of systems that he inherrited, but it was all under the Togakure Ryu name, despite almost none of it being Togakure Ryu itself. The name Budo Taijutsu came about in the mid-late 90's for the organisation.
In terms of Toshindo (and the Bujinkan) being essentially "business evolution", well, no. Toshindo is Hayes' modern application and expression of his years of training, and the Bujinkan is Hatsumi's organisation to teach the lessons he gained from the lines he teaches. Neither are "ryu" in any sense, both are organisations. Hayes' being American has obviously influenced the modern approach, but it has nothing to do with any form of "copyright" approach... remember that the traditional Ryu-ha (Koryu) are considered a copyright that is held by the current Soke, so copyrighting isn't odd or bizarre at all.
In very simple terms, Toshindo is not the Bujinkan, but has it's roots in it. Stephen Hayes was removed from the Bujinkan list of teachers/members a number of years ago now. The removal happened years after Toshindo was formed, and happened in no small way due to Toshindo being formed.
