Perhaps you're confusing VPNs with Tor. The latter seeks to provide anonymity; the former protects traffic traveling over a potentially untrustworthy network. Sure, a lot of
folks seem to use VPNs lately as just a proxy to bypass geoblocking or whatever, and that works if the upstream endpoint is in the right place - but that's no reason to get confused about what the tool under discussion actually is able to do.
A lot of people are using VPN providers to download illegal content via torrents. And in case there are no logs on the servers (which most providers advertise) the copyright holder has no way of knowing who you are since they only see that the traffic is coming and going from the providers IP address.
Those people are in for a series of nasty surprises if copyright enforcement ever grows teeth, because whoever's providing such a VPN service with backhaul certainly has enough information to tie them to their activity.
If they don't store logs they don't have enough information. That is the reason why a lot of companies that provide this service are incorporated in countries that don't require them to do so.
I can run a VPN service and not store logs. I can't prevent whoever sells me that service's bandwidth from storing logs, which they likely will do for troubleshooting purposes if nothing else.
The whole idea of VPN providers is that a lot of users have a connection to the same server so it's hard to monitor who talks to who.
