AFAIK Amithlon was never sold in any other form than the fully boxed 'retail' package by H&P. To sell systems equipped with Amithlon without including the fully boxed Amithlon package would be clearly illegal regardless of whether anyone is going to enforce their copyright or not.
The rules of this (and most other) Amiga forum is that such 'offers' cannot be discussed or promoted within and that should be the end of it.
Anyone attempting to make money by selling Amithlon (unless they are simply re-selling their own boxed copy of it) is a pirate. It doesn't matter one jot how you justify it.
