Well composed and likely destined to be ill-received for the same reasons that it's so accurate.
The only wrinkle I would add is that it was a legion of second generation evangelists that took up the mantle that the Amiga could displace other mainstream, general-purpose platforms. Their intentions were likely genuine, but in most respects it ended up doing more harm than good.
The yardstick for 'success' is always a difficult one. First generation Amiga users did not entertain thoughts of the platform taking over the world -- they hoped that it would survive and be recognized as a legitimate niche player.
Since OS4 was announced, Hyperion has always been more vocal in maintaining that running on a mainstream processor would erode the remaining spirit of the system and encourage piracy. The first point has always been troubling -- in the decade since Commodore evaporated very few people still exist with their head in the sand. It's not like we don't all interact with Windows, Linux or MacOS to some extent on a daily basis. The piracy argument is equally distressing. Target a market that will pay for products and services and forget the rest. Piracy is inevitable.
In the end, we've really had to endure 12 years of folly and the main culprit here has been those that own and ctonrol the IP.
Could 'success' still be achieved in today's market? I'm convinced it's possible. Can this be achieved with no clear vision and no one helming the ship? Hardly.
