I don't really understand the anger over A-EON not porting software it owns to MorphOS and AROS. That's like expecting Ford to start making accessories and parts for Toyota owners. They are under no obligation to do so and have a business of their own to run.
It would be nice if they did, but I don't begrudge them for not doing so.
Real Software Publishers will port their software to as many systems as they can in order to maximise sales, you are saying it is OK for A-EON to use software they own to kill sales of competing hardware, if that is OK with you then how long will it be before they sell software that ONLY runs on A-EON's own Amigaone systems?
