Well their original mantra was that they could only release OS4 for official AmigaONE branded hardware thus preventing Moana from bring officially available.
Then they released it for SAM boards and the Pegasos II after the court case so there is no rational reason for Hyperion not to release a Mac version.
If that cost ACube and A-EON business then they should adapt or die. That's what capitalism is about, competition and I'm sure Hyperion would make more money due to enlarging their market.
Are you sure about that? Trevor has invested lots of money in this venture. If Hyperion does that they might get some sales but at the same time they propably lose Trevor as supporter (or at least risk that). And it is propably a strategical decision to have their partners and only sale it on new hardware.
