When/how XFree86 was wronged, no flames pls

Hi guys,
I have the following question to XFree86 guys:
How and when were they wronged by people/firms taking unfair advantage 
of the older license?
I mean - in order to start the change, XFree86 guys felt that they were 
wronged. Will they provide real world examples of this?
This is just an inquiry, not a start of some tactical political maneouvre.
I've read the archives and see some examples of this - the fbdev 
situation (for example). (or am I completely wrong?)
Can you provide other real world examples because some people may not 
grasp XFree86 feelings or the shoes they stand in.

Best regards:
