I don't work with payments and the surrounding systems so I don't know the details of the project itself. As an organization we've certainly been aware of the feature request, but until now we've prioritized other projects.
> EDIT: I've heard a rumor that you've shared a user IP because of a government subpoena (live during a connection, so it wasn't logged). Has this happened?
To my knowledge it has never happened in the history of our service.
> EDIT: One other question - is there plans to add more IPs? Services seem to flag most mullvad IPs but I'm not sure there's much you can do about that.
I'm sure my colleagues in the Operations and Support teams are aware of it. You'll get a better answer from support@mullvad.net.
