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.
There’s some games that use peer to peer connection that can expose your IP if the person on the other end cares to do the digging. In some competitive games people that are trying and caring way too hard will use this to say DDoS people in order to win games. While I’m probably not good enough, or well known enough for people to be doing this, you’ll hear streamers mention it happening to them every now and then.
