“There is no such thing as a VPN that doesn't keep logs. If they can limit your connections or track bandwidth usage, they keep logs.”
This is factually incorrect, I have been running OpenVPN on my server for about 10 years and there is not a single log file - so yes a VPN can be configured to not log anything. I think what you meant was "there is no such thing as a VPN service that doesn't keep logs..." and I suspect that may be true (although there are several who claim they don't).
What the FBI did do here though is just destroy PureVPN's business as I suspect people will now run for the hills knowing that PureVPN is not only logging but working with LEAs.
