Given the recent Proton controversy, I imagine quite a few people are trying to jump ship on their services. I myself was already in the process of something similar for different reasons, and looking over the services I believe addy.io to be a better fit for me than simplelogin (or Eforw, which I haven't heard much about in general, but I have a membership with) And so I would like to ask the community here about their thoughts and experiences of and with addy.io

If you're able to explain their ownership structure and the like too, that would be appreciated, given that proton is a non-profit, which is an upside for it.
