I just say revoke Common Carrier status and all protections thereof - namely the protection to not be sued for its uses.
The one thing the DMCA got right is that a common carrier should not be liable for what use it was used for (this is why web hosting companies cannot be sued if one of their clients puts up a website filled with illegal materials). So, if they want to get rid of net neutrality on their lines, as far as I’m concerned they are no longer a common carrier, and should be opened up to being sued into the ground and called as a co-conspirator in every internet-based lawsuit that happens from now on.
