I am not sure that I really understand what they did. I am also missing some major VPNs in the list. I currently use AirVPN but this has something to do with my use case and pricing.
Why do you want to use a VPN?
- Privacy
- Anonymity (hint: don't!)
- unblock geolocation
- torrents
- GFC
The last point is the hardest.

They checked where the VPN exit nodes are physically located. A lot of them are only setting a country in the whois data for the IP, but do not actually put the exit node in that country.
