I tried Mullvad Vpn and I liked it. Plug and play, 5 € p month, 5? machines, speed ok ( 220 Mbit/s ish on ookla), no other BS. Also you can choose anonymous payments, which is a big plus.
Proton for email wasn't intuitive to me at all , some years back. Don't know about their VPN.
Also, Sweden is in the EU and CH (=Switzerland) has EU association, so kind of copy pasta concerning privacy rules and citizen rights. The former famous old-skool CH privacy is long gone, if that's what you were thinking.
Most (good) VPN have quantum encryption, which Iike many said, is a bit of sales pitch bla bla imo.
So do I undertand you correctly it's just an "eventuality option simulation" to lower the environmental footprint?
Like for example the listed WLTP* Kw/h / fuel consumption of cars in perfect (lab)conditions which never exist?
*Worldwide Harmonised Light Vehicle Test Procedure
