Moth to a flame: I couldn't help reading up on it.
Just my layman's POV but it look like it has been going on for over a decade.
If I have it right Ianucci was around from the very start of AHRMA and was instrumental in getting its status as a non profit organization. As part of that original incorporation he was supposed to be ~"Special Advisor to the Governing Board."
There were two different interpretations of Special Advisor. Ianucci thought it would give him licence to attend and comment at board meetings. The governing board thought it gave him the right to comment if asked and don't ask, so he was pretty much shut out of everything.
Since then it has been what can only be called a 'king of the rude' contest with both sides running neck and neck to be king. Team Obsolete has been banned from AHRMA events and on at least one occassion the decision was delayed for a week so the shipping of bikes and equipment from New Jersey to California had already begun.
When I first started looking into it I thought it was going to be a slam dunk with T.O. in the wrong. After looking into it I have concluded it is much more of a mutual cat fight. I mean AHRMA filed a lawsuit against Ianucci because in his venues he had a BEAR class<British, European, and American, Race?> and got a court order that he couldn't use the term BEAR. Petty, petty, petty!
Everyone interested in vintage motorcycles suffers because of this stupid fight. Money that could be spent on things like say, vintage motorcycles maybe, ends up going to legal fees.
