Why do you think that is? You can't be the first ones to think of allowing fans to control teams. Technology just now catching up?
The major professional sports leagues offer an incredible product. They have tradition. But tradition also carries with it some encumbrances. They are tied to it and slow to adapt from it, even when doing so would be an obvious win for their organization.
They constantly worry about change and how it will affect the relationship with their fans. Even something as seemingly mundane as putting an advertisement on a jersey is celebrated as monumental innovation.
The idea of technological shift isnt just unfathomable to these leagues; it would represent a complete deviation from the story they have told for decades.
