AirVPN (VPN Services)

Here is how they explain it:

  • Only online users.
  • Data collected from current sessions in real-time, that we inevitably known. No history is kept, no data-retention is performed.

As to:

Even worse, they have a ranked list of longest connected users… those users haven’t rebooted their computers for security updates

My assumption is that anyone on this list are using a VPN at the network level, on a router, a network appliance, or maybe a seedbox or server of some kind. I know some people are weirdly opposed to updating or restarting their desktop, but I don’t imagine even those people are going 6+ months without ever restarting, shutting down, or logging out.
