Making ISPs liable for users' piracy is transparently transferring the costs of policing "Intellectual Property" to ISPs, and at the same time, making it easy for "Intellectual Property" owners to sue for damages - an ISP has a fixed address, legal counsel, and deeper pockets than most teenagers.

No, ISP’s are common carriers. You don’t go after the telephone company because someone coordinated a murder over the phone line. Why the hell would an ISP have any responsibility of what their users do?

This is just bad law. It opens up culpability in all manner of supply lines. Are water companies required to detect and report leaks? No, that responsibility falls to the consumer. The water company does profit, (as does Cox but not disproportionately) yet the water company still has no responsibility to detect or report leaks.

Only if gun manufacturers are liable for murders.

So what would that mean in practice? ISP's would buy into some stupid "great firewall" thing built by, say, McKinsey, that works in the most obvious cases, so they can claim "they're doing their part"?

Sony Music has zero reason to guard against false positives if they win this. Innocent people are going to have their service canceled.

What are the odds this SCOTUS makes the right decision?

End users should be liable, and ISPs should not be required to give user information to claimed copyright holders or forward notices.
