I hear you on the tinfoil hat.  Part of this is not per say they are getting your data, but also about control.  One of the members of our chat group was talking about being banned from proton for sending business emails in small bulk.  He was saying how it was fairly small amount, but he lost the account.

So it's about privacy yes, but also control over your digital home. 

 I can get that, but it sure is a lot of effort to manage a self hosted email. 

 Understood, that's why we're trying to help people to make it fast and easy.  Now does that have trust in us? Yes.

But the goal is to get people in a place where they are more self-sovereign 

 I can get behind that, cheers!
