The whole point of establishing the hub is to disrupt the academy realm.
The best way for doing that is to undermine the authority of the Academies. That day, with Icarus' threat, Sam showed exactly that. The Dean of the Zeus Academy, one of the most powerful people in the Academy realm had to back down.
Sam is sure that most people would notice this and the Hub is bound to face some friction.
However, it is too early for the hub to receive that much heat. He needs to create some sort of distraction. Even if the upper echelons want to focus on Hub, they should have their handful with other things.
They shouldn't have any time to deal with the Hub.
Luckily, he already started the plan. The puppet that he gave away to Raios and the three puppets that attacked him are part of that plan. He is sure that someone must have noticed that battle. Even if they didn't, he is planning on giving out the recorded video of the battle and spread the information.
