If the actions of the families made waves, Sam straight up created a tsunami.
The fact that he even offered the hub's technology, made them wonder if Sam is just an associate of Joker. If they didn't know any better, they would have thought he was the Joker...
They would have thought the same if they actually choose to accept facts. But in their minds, Sam with all his might, is still far away from creating something like a hub.
As usual, people judge others by their own measly standards.
Anyway, the academies that were previously trying to stay on the fence and see what kind of disturbance Sam will create now became heated.
Even before the families realized, forces were deployed. Not just to attack the people who were already in the academy realm. But instead, directly went to their planets and realms. Before Sam took away the next victim, the families went through a slaughter.
