I have been paying for Proton Unlimited for a very long time. About a year ago, they changed their prices for new users. currently it is $12/m, but I have to pay only $7.50/m, and yes, I pay monthly.
I use Proton Mail with 3 custom domains, and I am an always-on VPN user. The VPN connection is always great with good speeds, but sometimes bad pings, but have a bad Linux app (yes, the new one as well). I also use their drive, currently using ~200GB. I have never touched Proton Pass because I have a self-hosted Vaultwarden server.
But I am seriously considering discontinuing their service, specifically due to their poor Linux support. Their VPN app is shit, they don’t provide and not even developing a Linux app for Drive. But their are 2 reasons that make me continue their service. One, I do not really wish to self-host my email, and I do not want to use Tutanota, because I need Thunderbird. Two, there are no trusted VPN providers that give Indian IPs.
