Yes, I thought about that as well, but if possible I would prefer to retain the original data (also I just like to tinker with stuff :) ).
However, like you said, they’re doing some “spatial” stuff they don’t disclose. I assume it’s just some EQ, but if they really have some algorithm to compute HRTF or even they’re own audio format, then re-recording might actually be the only solution.

This is old and false information. The incident in the link happened already a decade ago and laws have changed since then.
The current situation is that they need to prove it was you and not someone else in front of a court, so if you tell them it wasn’t you but someone you know they’d need to open up a court case which is way to expensive for them and that’s it.
Also what are you on about „citizens reporting on each other“, lol. This is some lawyers who found an easy way to make money. Those exist in every country. Also everywhere „private companies“ (aka lawyers) can make investigations and go prosecute someone. That’s what they’re for.
