One summary easily stands out, delivered by a user who goes by the moniker 'jugalator':
I'm putting that here as I thought it was one of the better overviews of the situation as it exists today.I think Hyperion is best suited for new development. They did a mountain of effort for AmigaOS 4. They have (had??) ambitious goals for AmigaOS 4.2. Their dev team is admirably well versed in the Amiga operating system despite its age and small niche today. If they wanted to make more conservative updates, they could probably also branch Kickstart 3.1 into a 3.1.x or 3.2.
Cloanto seems more about keeping dat nostalgia... and rights to the classic Kickstart etc... alive. They want to bundle all that classic stuff for an as slick experience as possible. As far as I understand, this puts them in conflict with Hyperion who also claims rights to at least Kickstart 3.1 as their development base (otherwise AmigaOS 4 wouldn't have come to life). I have no idea how this could have happened to begin with. Where did Hyperion get their source code? Where did Cloanto get their source code? I don't understand how this conflict even happened. They sit on the same intellectual property??
Amiga, Inc seems to be about making money and probably not caring all too much about the Amiga to be honest, ironically enough. They appear to be the most interested in making best use of the trademark and use Hyperion developed stuff for new ready made systems. They aren't very good at this. I doubt they understand where the market is heading or the best strategy forward, if they even care much.
I wish Amiga Inc would be out of the picture, and Cloanto + Hyperion would merge. I think that would be the best solution here. Both of these always seemed to have more of a genuine care for this computer.
Legally I read Amiga Inc has lost their US trademark for the Amiga brand a few years ago, but claimed them for EU until 2021... So maybe it was just matter of moving their web site to a European server, lol. :p As for Cloanto, Hyperion, I have no idea. Surely both somehow have papers on the IP? Again, I am missing a link to how both came to claim the IP in the first place.
While they are trying to kill each other off, you see stuff like Apollo taking more and more place. They have sort of become the builders of the next gen Amiga to me. Looks like they have the most sane, pragmatic hardware way forward to bring the best performance/excitement per dollar.
My own personal wish is they'd both simply release the IP - especially Cloanto. Put it into the community's hands and let it become open source. Allow us to freely use and distribute the original code - code Cloanto never made themselves. Then, over time, the community might enhance older versions here and there. Surely the money Cloanto earns must be tiny to say the least. But the potential benefits of releasing the code to us crazy folk? Huge.
