This is for the user to decide. You cannot demand that everyone make the same decision about the trade off of privacy vs self-custody simply because you have a preference. There are very real trade offs with the options you present, the worst thing for UX is to presuppose what trade offs the user wants and centralizing risk into one design for everyone despite the very different needs.

It's about teaching the difference between these risks and letting people choose, not choosing for them, imo.
