Privacy

I'm still relatively new to Proton, but I thought I read early on that they would still have to comply with legal requests. I believed that their system was mostly in the realm of two secure accounts being able to hide the messages themselves. I use a card, so I am tied to my account. Does using whatever coin they take (if any) help with this? I remember reading they wanted to open more doors to alternate payment methods. I think it was to help privacy but also in large part so that they could still collect money if they ever get slapped down by other processors for making someone big mad for their privacy setup.

EDIT: I thought I had replied to something like this before. Found it. https://a.lemmy.world/lemmy.world/post/15148279 It seems to me that some just overestimate what the service is.
