This is a murky and highly debatable topic, with lots of grey areas.
Regarding the potential loss of revenue alleged by record companies to denounce mp3 downloads, the same could be argued regarding amp profiles... with the same weak reasoning. The fact I am able to download and use an amp profile, whether free or commercial, does not mean I will not buy that amp nor I would ever consider buying that amp in the first place. Just like with music, digital media allows users to sample and evaluate content, and ideally later "vote with your wallet" by purchasing relevant and worthy content.
The key issue with "illegal" profile exchange boils down, IMHO, to an infringement of the applicable Terms and Conditions by those who purchased commercial rigs and decided to share them, even when that behaviour was explicitly prohibited by the T&C.
In Spain we have a saying that goes like " you cannot put a closed door in an open range..." (no se pueden poner puertas al campo) and the truth is that morality governs digital transactions, rather than copy protection or legal enforcement. It is the Education of the users, and a decent and just pricing policy, that should be used as a countermeasure to illegal downloads of any kind.
