And the NordVPN section is silly. It only references some random anonymous VPN review (aka probably someone from PIA).
For everyone just tuning in, BestVPN is one of the top English-language VPN affiliate review sites. They get paid when you signup for a VPN via their site. Their "rankings" are exactly lined up to how much profit they make off your clicks.
You'll note Nord is their #3 "Best VPN Overall." I'd guess the shade they're throwing is a move to improve their negotiating position.
