I've been using VPN services for over a decade. In my opinion, the most privacy friendly are AirVPN, Insorg, IVPN, Mullvad, Private Internet Access and Riseup. To my knowledge, HideMyAss, EarthVPN, IPVanish, PureVPN and WANSecurity have violated their users' privacy. For the most part, by sharing logs with investigators. Prudent providers make damn sure not to have any logs that could be seized.
Well, I will not advocate for any big brand here but it is also true that hidemyass, IPvanish, Purevpn has more than 50% total share of VPN users and indeed its true that new VPN services especially Private Internet Access is going great. I recently read some review of them at Bestvpn.co.
