Rumors abound in amiga land.
I agree that if your going to make serious accusations like that, you should present evidence.
I've heard this rumor myself many times, but then I've also heard that they used an awful lot of aros source code.
If they are using aros source code then closing their own source and charging for the resulting product, I find a bigger problem with that.
Of crouse, I don't have evidence of morphos taking either os3.x or aros source code to use in their os, this is just some of the things people have said over the years.
