I was going to stay out of this... Remarks here are only in regard to the ethics question, not the integrity, performance or desirability of The coolest piece of gear I've ever owned!!
Although I agree that the question concerning the "ethics of profiling" is one that may need to be addressed, I disagree entirely with any conclusion that it is "stealing".
As several people have already mentioned the KPA only "clones" a particular moment in time. All conditions present in that moment are, just as with a photograph, ultimately crucial. Amp settings, cab, mic placement, the room, etc. Not mention the outboard specifics of the session (preamps, processing, blah...) and the skill and experience of the profiler. Snap. Just like a photograph, there's your "moment". From there, although it is possible to fairly approximate some of the amps behavior with the available control set, just like the photo, you can only go so far before the soul of the moment is no longer present. To capture the entire soul of the amp you could work for an infinite number of lifetimes trying to snap every possible combination of settings and the result would still not be a clone. It will be a collection of representative photographs. Reproducing the amps DNA using the KPA's current technology is impossible.
