Privacy Pass would decouple each search from the account. I think it’s okay to have as an opt-in thing. But private payments should be the default IMO.

I see. I mispoke with "privacy pass" although it's similar. I meant like a one time break between your payment and account for regular accounts underneath the option to use privacy pass.

Like posteo does it or Brave does it for Origin:
