Proton and its services have been pretty good. Some things to know about proton mail:
The VPN had been great
The storage isn’t enough for me to be able to move off of my main cloud provider. There also isn’t a way to pin a file on Android for it - and the 500gGB of space is less than I use
The Pass app is handy and it’s easy to make aliases, though it often doesn’t know to fill in, doesn’t do it, or something, and I need to open the app to copy paste. Pretty trivial though.
I’m sticking with them. I don’t really have a reason to leave. The aliases are really nice, the catch is that it’s not easy to have them go to a sub email address that I use - it has to go to your primary email. Not a huge deal though.
You can open up just about anything and unplug it
