That's how it supposed to work, free RAM does nothing :)

I can not be, nextcloud was just an example. I have never had an issue with nextcloud backups

Proton is starting to loose focus in my opinion. I've been a costumer for 5 years only using email and I moved this year to fastmail and I couldn't be happier. Unlimited emails alias, good apps, ability to use thunderbird without a self hosted bridge.

The promise of a encrypted email does not work if your contacts are not on proton too (for me was 100% of my contacts).

If you are really focused on privacy you would choose nextcloud for cloud for example and keypass or Bitwarden for password managers.

I would like them to focus on email client features and stop this side hustles.
