It was a good chart but stopped being updated around 2018/2019. I don’t remember the specifics but IIRC the owner (That One Privacy Guy) sort of ran out of time / retired from doing that stuff. He was also active on Reddit moderating VPN subs for a while & was great at keeping out the VPN spammers/shills there.
He had his own website that was bought by SafetyDetectives (a spammy ranking / affiliate linking site) so for a while people were worried that the new owners would break the VPN google doc with paid referral listings & whatnot. Kind of disappointing that it would be bought by a company clearly promoting the opposite of what That One Privacy Guy was working towards.
I’m not sure if that Google Doc you linked is a copy, or maybe the last version that existed. It was never totally clear if SafetyDetectives actually got control of the Google Doc but the rest is history now.
