@cgutjahr People use AmigaOS because it works better on their hardware, not because it is official or not. There have been numerous much better Operating Systems for the Amiga from a technical point of view (Linux and NetBSD), but they fail to deliver the perfomance users expect on anemic hardware. Add to that the nostalgia factor. So competing OSes on Amiga hardware are nothing new and the fault is not somewhere else but theirs to carry.
I could work for Atari, Apple or your grocery shop just around the corner, I don't care what company drives AmigaOS. What I do care is my hobby, and have someone that supports it.
Hyperion is absolutely flawed on many fronts, but they at least give us the freedom to decide the route the OS should take, and offer a basic support for that. Cloanto does not offer anything at all. They have never approached us with any sort of plan or proposal. But hey, if you are happy enough with Amiga Forever then be my guest. It is your hobby too.
It is simple, those two companies are expected to keep doing what they have been doing, everything else is mere fantasy right now:
Hyperion will continue selling AmigaOS
Cloanto will continue selling Amiga Forever
Then as a customer you can use your wallet to vote for your choice. That is the best you can do.
I do hope Open Source comes to AmigaOS, I even believe it will inevitably arrive, but it will not be in the timeframe nor shape people expect it to happen. And for certain, some entity formed by developers willing to work on the OS must take desitions on the roadmap, or otherwise it will be just another dead OS project in github/sourceforge.
