> to a different, often less-regulated ISP "Less-regulated" is usually the entire point of using a VPN. Regulations force your local ISP to keep detailed logs and reveal who was using a certain IP address at a certain time to various entities based on sketchy circumstantial evidence. If you go through a VPN then anyone trying to track back the IP address has to go through the VPN provider first—who probably doesn't keep such detailed access logs, and may well be in a completely different jurisdiction—before they can even begin to approach your local ISP. You certainly shouldn't rely on it exclusively, but it's an important part of defense-in-depth.
