Even the pre 1994 Commodore might not have had the full source code rights to all the parts of Amiga OS 3.1 and below. Over the years they licensed screen fonts from Adobe, outline font stuff from Compugraphics, the speech stuff from another company, ARexx, tripos dos stuff and so on....
For an open source enthusiast, it makes more sense to support AROS m68k-amiga achieving a release state that's at least as capable as Amiga OS 3.1 was/is.
