Full disclosure: I work at Private Internet Access.
Best recommendation: Get a cheap server from LowEndBox and setup OpenVPN (or, hopefully in 2019, WireGuard) for your less tech-oriented friends.
They don't pretend a VPN is going to keep you anonymous (https://encrypt.me/what-is-vpn/) but rather pitch their platform as a way to stay protected while at coffeeshops and public networks.
I used them when I was freelancing and working on public wifi. Super easy to use and reliable.
It's still possible to setup by copy pasting a config file and downloading openvpn- but not as convenient as the regular application.
I was with Private Internet Access before and will either switch back to them or possibly to TunnelBear in the near future I think. The last 6 months with NordVPN has been pretty terrible.
