> My reason to drop it is that I want my data out of the US for privacy
Given most cloud providers use AWS as a back end, that's probably not possible. Plus, if you send email, it likely will hit a gmail,hotmail,etc. server. It's basically impossible to avoid.
I use web.de for email, which is the largest german mail provider in Germany. Their data center is on the other side of my city. Unfortunately, they are somewhat spammy even if you pay. I think about switching to mailbox.org or posteo.de.
Sure, lots of my contacts use gmail, but since email encryption is not really used, email is practically unsuitable for secure communication anyways. Fortunately, we have a few good instant messengers (Signal, Wire, Threema, ...) now. The primary use for email today is authentication, so I should probably get my own domain to maintain control.
My replacement for Dropbox is SyncThing. There is no cloud storage. It does not provide sharing via public link of course.
Mailbox.org does E-Mail for over 20 years [0]. ProtonMail only exists for 3 years [1]. Thus, I give Mailbox.org a higher chance to be still around in 10 years.
ProtonMail does PGP via Javascript in the browser, which is ridiculed by security people. Mailbox.org tried that in 2015 and it did not survive their internal pentesting [2]. Maybe ProtonMail has better coders. Maybe not.
Mailbox.org smallest offer is 1€/month. ProtonMail lets you choose between nothing and 5€/month. I like the mailbox.org price point.
If you believe in secure communication via email, you should support ProtonMail. They try to make it hip and easy. In my opinion this is a lost cause. Even if we could educate the masses about PGP, this is still behind the Double Ratchet Algorithm [3].
