I wonder how much the ISPs will invest based on the current regulatory rules. Net neutrality could be revived, especially in a few years after the next U.S. presidential election.

Businesses usually want certainty so that they can invest in the future. In the state where net neutrality is repealed, there is far more uncertainty; it could be revived any time. If the ISPs accept the state that net neutrality is implemented, there is stability and certainty going forward.
