The major US ISPs threaten not to make any more investment if the FCC maintains network neutrality.

This article says they are bluffing.

If we give in to threats from businesses, they will push us around. We must treat them like any other bully and tell them that we will never give them what they want for threats. If they threaten us, we will make them regret it.

We could do as some other countries do, and separate the physical cables from ISP service. That way we could have a lot more competing ISPs that communicate over the same cables.
