I agree with the above.

However, from my experience in CAD, Wikipedia's notability and importance ratings are strongly skewed towards open-source and against commercial systems.

High-importance:

https://en.wikipedia.org/wiki/Talk:FreeCAD

Low-importance:

https://en.wikipedia.org/wiki/Talk:SolidWorks

No disrespect meant to the FreeCAD folks, but that is definitely back-to-front! The article on Solidworks lists 165,000 companies using the product as of 2013. How is that low-importance?

The skew tends to be even worse against enterprise class systems.
