Swiss company Proton is further expanding its productivity suite. In addition to an email service, calendar, VPN, password manager, and drive, Proton Sheets is now available. It is an alternative to Microsoft Excel and Google Sheets, an increasingly important advantage as countries take sovereignty more seriously.
I’m in a similar boat. I had Proton Unlimited because of a good deal they had, downgraded back to Mail Plus and got Mullvad for VPN (which looks to me better than Proton).
The thing about Proton is they make it easy to degoogle. I can easily set up gmail stuff to be forwarded for things I didn’t switch yet (or people who didn’t catch on the fact I changed emails) and they have a whole suite of products.
But really, if Tuta introduces a Drive on feature parity, I will consider a switch - though it will be pain to change everything again.
