Register-free access to VPN (critical for countries like Iran)
In countries like Iran it is very complicated to use proton vpn for very strange reason : it needs registration, and because proton VPN is blocked you CAN'T register. It is very critical thing for countries that block vpn very hard. Recently proton VPN released Stealth protocol. I think it's good idea to let users connect before registering, allow 50-100MB traffic, it is enough to register.
Once again, for people in countries with strong censorship it will be life saving. Please do it, Stealth is the only protocol that works in Iran.
I would support this as there may be whistleblowers and people needing help who need access to the VPN. Many nation-states have very limited free speech, but VPNs like ProtonVPN help people speak out against an oppressive government.

yup, free services should be accessible before registration. having servers' info in the installation file also helps when protonvpn is blocked somewhere like Iran. in addition to that, stealth protocol is not working in Iran. (internet access for the public, I'm a student and when I'm at my university it connects normally, but not when I'm home.)
