yes, my ex gf from iran also used Psiphon, I didn't trust psiphon that much but it seems that its decently well

In the end I had suggested her protonvpn as psiphon had some issues.

How does Psiphon work and how does it compare with protonvpn? I still trust protonvpn (which has free access as well) more than Psiphon fwiw.
