Any lawsuit would have to prove loss of revenue. I'm fairly certain that a good lawyer wouldn't be concerned only with the name of the profile.
For example, if they could definitively prove that the existence of a "Fan Double" amp profile leveraged Fender's reputation and reduced Fender's revenue, then Fender could win damages in court. I for one am less tempted to spend $2000 on a specific amp, if I have a profile that gets me 97% of the way there. And those "commercial" profiles are supposed to be better, so they would potentially make buying a new amp completely unnecessary.
The bottom line is that the fiscal ethics of copying a sound for profit is dubious. Making copies of copies of sounds is no more or less dubious.
Long live the RE!!!
