I've cancelled my subscription yesterday, conveniently it was about to renew at the end of the week, so I have a few days to migrate from Proton, here's what I'm thinking of, but I'd love to hear what other people are switching to
Instead of bitwarden, i can recommend Aliasvault. VPN, well i made some good experiences with Xeovo. As for drive, i really like nextcloud myself which also has meet and chat. Filen is a good cloud too i think.
