*The Bonannos (post 1968) aren't the same organization (or drawing from the same historical lineage). And lost power, prestige and money.

This is where I have to disagree with you. The Bonannos are still very much in touch with their roots, even to this day. According to Italian law enforcement:

Francesco Domingo, is the Mafia don of Castellammare del Golfo, in the Province of Trapani, Sicily, which is likely the birthplace of the Bonanno Family. According to various investigations, Domingo has maintained close relations with the American Mafia, in particular the Bonanno Family. In fact, Bonanno affiliates have made numerous visits to Domingo's villa in Sicily. Here they would ask Domingo for permission to speak with members of the Mafia family based in Alcamo, also in the Province of Trapani. The traveling Bonannos also conveyed messages between Domingo and his associates in the United States. Domingo was arrested in June 2020, along with 12 other members of the Castellamarese Family.

I think many of these so-called "experts" talk out of turn, or speak too soon, without knowing what the hell they're even talking about. The Bonannos were indeed still a powerhouse after 1968, and while they may have been booted off the Commission, they still held their own and were probably the Family with the closest ties to the old country.
