Not only this is a feature that I, as paying Proton Mail user do not need, but having it as a premium option will probably end up pestering me in every possible way: emails, UI elements, popups, etc., to upgrade to feature I absolutely detest. I tried to get away from Google and their nonsense, but actually ended up in the same place. Are there any decent email only providers left, without "AI" and load of unnecessary apps that they keep purchasing each week? And still, no Proton Drive for Linux.
