Filen does photos too, so you could consolidate 2 and 3 into one. I went and bought 500 GB lifetime storage on their Black Friday offer. Let’s see if they stick around. So far the experience has been smooth.
And if you mention mailbox.org, let me throw Posteo.com into the mix. Basically the same offer, but where mailbox presents itself a bit more business-like, Posteo seems to market itself towards individuals. I moved my mails there and are quite happy with it, but you have to roll encryption yourself. No auto solutions like Proton or Tuta.
Oh well. Nothing screams healthy business like force-feeding your product to every customer who can’t hammer the conveniently hidden opt-out button fast enough. I’m sure Gemini is doing great.
