I daily drive Proton mostly because of speed for gaming, but I keep a mullvad account handy for special occasions. I have zero interest in the full Proton stack, I don’t want to centralize my data like that. Especially once they joined the AI train, I’m glad I kept my VPN and email separate.
I host my own private git server and use Unix Pass for my password vault, FastMail for email, Syncthing and SMB for file sharing, don’t really use crypto so I couldn’t care less that they added a wallet. The VPN interface on mobile and Windows/Mac is fine. I’d love to see the Linux options improve, but I just use OpenVPN profiles and it works well enough.
