I don't know what Nintendo's ultimate goals regarding the Smash and larger competitive scene is. I certainly don't blame them for wanting to wash their hands of the scene completely and forever after the events of this summer. Which by the way have not exactly been completely washed of from said scene,
because one of the offenders was recently spotlighted in that new Melee scene documentary:
Their business of how they handle people in the community is not always agreeable, but Nintendo have just reasons for making their moves (again with events having to do with being licensed, trademark infringements, etc.).
I see Nintendo's point of view in these scenarios because I can grasp their reasonings. I'm not in the group that tries to push their buttons and then act surprised when said company isn't happy.
