Why doesn’t Proton strongly encourage paying anonymously like some services and do they log more data than others? Is this concerning for you?

Ah that article. The author seems to believe Proton should somehow operate outside of Swiss law and be exempt from the MLA treaty. What company like Proton can operate above their local laws? We shouldn’t blindly follow any company, but rather read their terms and policies, and use aliases. The story in that article mentions a Facebook page that used the primary @protonmail.com address as the contact, which isn’t wise if you seek anonymity. I wish they did Monero directly (or similar) but you can use Monero though a proxy payment if i recall. Cash is still great though. But if you need to operate secretly from your local government, then I’d suggest not using any providers mail domain and a credit card.
