From current events, you'd think so.
But if that was the case there wouldn't be so much friction between AOS4 and MorphOS camps.
Okay, think about this for a minute.
OS4+MOS=friction
OS4+AROS=friction
OS4+Real Amiga (68K)=friction
Where is the friction between MOS and AROS and 68K? See where the divisive factor is?
