VPN’s to me have limited usefulness. Its basically just buying a new endpoint where your first one is your isp. The big thing is if the vpn does not keep logs and/or runs completely in memory. I mean your isp could do that but I don’t know of any that make the claim. You are pretty much relying on the vpn doing what it says it does privacy wise. Besides that it can be useful to seem to come from a different physical location but again the logs of the vpn would say where you came from.
