To replace everything. Mail, calendar, drive, vpn, password manager, documents etc. What are the pros and cons relative to proton? What are the mobile apps like? What assurances do you have they won’t go full proton in the future? And other questions
I get the controversy about the CEO being controversial but the services that proton make are still very good for the most part. And since they’re open source and encrypted you don’t need to trust proton anyway (aside from the VPN).
