Commodore made lots of bad choices, but the argument I made here is that those bad choices didn't really start to happen until 1993 and by then Amiga had fell far behind the PC. That is what needs explanation. Here is where I believe the "it is a toy" attitude played a major role.

Commodore was not able to sell anything like the PC in those several years where they had a superior product and had not made an particularly bad choices.

Compaq reverse engineering the PC, was IMHO an outcome of the large volume that IBM PC sold. Had Amiga been in that position, then Amiga clones might have existed.

It was not that unusual to clone stuff. E.g. home in Norway we cloned CP/M. They built an OS which had the exact same API as CP/M. That was because at the time CP/M was very dominant. Had Amiga been dominant, we might have seen it cloned as well.
