People,
Stop this Microsoft paranoia. Microsoft is just telling upfront that they think they have IP related to OpenGL. Now it is the task forces to see how this can be worked out. This is a normal procedure.
If microsoft would have played it dirty they would have kept silent and squashed afterwards everybody who was using their IP.
Fats.
PS: I also prefer other OSes to microsoft but this doesn't mean I need to be Microsoft paranoia.
