like Karlos said it's just way too long a story to explain briefly but after the demise of Commodore in mid 90's there were various camps of how to continue the Amiga OS in the future and let's just say that politics, passion, & wars etc. ensued.
Lots of stuff on the net to search for when you have spare time but let's keep this thread on the good people that make amiga.org a great place for Amiga fans;)
