Not sure if anyone is following the thread on TGP (maybe someone posted it in this thread and I missed it?) but the tech from Diezel chimed in and explained that the device does not prevent profiling the amp, instead it simply remembers that the amp was profiled. The point being to give the dealers a tool to know when someone has purchased an amp to profile it and then return it for a refund. I'm going to be honest and say that I think this is a good idea, it does not seem fair that someone would purchase an amp, profile it and then return it for a refund, especially if they sell the profiles. I have no idea how often this happens but I suspect that it does to some extent.
I've posted over there on this; anything beyond just gathering information is a risk to them anyway. If they were to cut the amp out in some manner believing it was profiled, at a minimum they are opening themselves up to a bug that could disable amps and aggravate their customer base.
I definitely get the "buy the amp to profile it and send it back". It may be legal and within the framework of the seller/buyer agreements, but I'd argue that it's wrong, particularly when a profit is being made. That action violates the good faith existence of return agreements. Just because something is legal or agreed to doesn't mean it's the right thing to do, particularly with companies who go a long way to make sure customers are taken care of.
Even if you're not down with profiling and think it steals IP (I don't know of IP that exists that is simply things like frequency response and transform results, but I don't agree given my knowledge), there are lots of people who own the amps they profile and use it for convenience, including mid to high end touring artists. It's not as simple as "bought a Kemper, didn't own the amp".
