You've researched this topic more than me. My citation is just knowing lots of people who have received the warning notices and concluded (quite reasonably IMO) that their ISP and/or government is more interested in the rights of copyright holders than those of their customers / citizens and sought solutions to that problem through VPN services.

The point of my post was not about this particular legal issue but about the general fact that ISP choice being largely limited by physical location means that it is easier to choose VPN providers that have interests more aligned with mine than ISPs. Whether ISPs are forwarding threatening letters from copyright holders or giving them contact information directly is not particularly germane to this point.
