I normally don't use VPNs, so please correct me if I am wrong.

I think from a law enforcement/accountability standpoint, if an "actor" is accused of wrongdoing while using Mullvad's port forwarding service, Mullvad might have some evidence linking the "actor" to an actual identity, since they have the payment information. Depending on the laws of whatever territories, Mullvad may be compelled to leak that info to a judge. Without that information, then there's no information they can ever be forced to leak.
