@skinnylatte This is very misleading. Proton never claimed you would be anonymous. They do not collect user data, the maximum they can have (if I'm not mistaken) is your IP, backup email and credit card, if you paid with one. The rest is end-to-end encrypted.
In this case, the account was a premium one that was paid with a credit card. You have ways of getting the subscription more privately, and this was a case of bad OpSec.
Please don't spread FUD.
