I was a big Amiga fan, but the reason it failed wasn’t because the big boys were mean to it. The OS was seriously flawed - the lack of memory protection meant it was not a safe thing to put any meaningful data in. As the world became networked it would have been a disaster. The tight integration between hardware and software was also a fundamental problem. It gave Amiga a head start but it also defined the end of the road pretty well too.
Moore’s law and ubiquity beat custom hardware every time. You just have to wait.
