Being real, after the debacle that is Google happened, I refuse to put all my eggs in one basket again. Proton is great at mail, so that’s what I use them for. The only other thing I’ve considered using is their calendar because there’s really no great option for me other than Google, because of the need to have an account that everyone can use on any device. Since that includes my dad, it limits things a hell of a lot. Proton’s calendar is still something he struggles with for some reason.
Bitwarden works well for me, so I ain’t moving.
Proton VPN is good, but mullvad is better imo, or air if I ever need port forwarding again.
And, there is the money factor. I’m fixed income, so proton is bloody expensive for me. I can’t justify the extra any given service would cost, even if I wanted a single provider for everything.
Don’t get me wrong, their fee scale is solid. Enough that it shouldn’t run dry for them and need more monetization, but not so much that it isn’t affordable for most. It’s just outside of my personal budget.
