I would say, yes.

Two of the principal families that had large narcotics interests at the time were the Gambino and Genovese families. Neil Dellacroce obviously represented the Gambino side, at a minimum, in a dispute with Galante that was all centered around narcotics. Since Neil was a member of the Commission (an Underboss) one could say that if Galante was excluding the Gambino hierarchy from investing/sharing in his pipeline, he was also excluding Dellacroce himself.
