when the infamous cracking groups that killed the original Amigas
A bit off the topic of this thread, but, crackers didn't kill the Amiga.
In fact, many people I knew back then got an Amiga over a Megadrive or SNES specifically because they knew they could get games for free, so in some ways crackers "made" the Amiga the success it was.
It was the lack of development on the hardware side, lack of new "big-name" software, and the eventual domination of the PC that killed the Amiga.
