In my opinion clock is ticking for "analog" and quite soon "digital" will be the only viable option for most musician (the gap in quality is almost bridged, and prices of digital will be only going down). Analog amps will join other technologies, like vinyl plates, which are reserved for collectors or just someone who would like to add some "vintage vibe" the their lives. This evolution can't be stopped, and happens very often in the world. DRM won't save it. Of course it is sad for vendors of technologies which are in decline but that's how things are progressing.
Kemper started this evolution by offering first true "tone replicating" machine, but it is clear that in a few year all major vendors will have something similar or modeling technology which will be perfectly capable of simulating or even synthesizing arbitrary circuit (Fractal is leading here, but in context of this discussion I don't see major difference between modeling and profiling). If not Kemper - someone else would do it sooner of later. I think the only sane way of rewarding amp manufacturers for their effort is to buy profiles directly from them (or maybe some merchandise). Sadly very few of them opt into this and sell profiles (Victory Amps is one good example - I bought their packs and enjoy them every day - Kraken, V40). Most people in this world are good and I'm sure wouldn't mind spending a few bucks to support their favorite amp builders, if they had opportunity. Why most amp makers don't sell their profiles?
