I certainly stand corrected, I made the assumption that OpenGL was open source (which was incorrect)

The assertion I was intending to make was that widely used open source applications tend to be analyzed and improved by a larger community and thus are more likely to be more steamlined/efficient ("faster" was also not a correct term here to describe efficient pipelines)

Although as someone stated further down, OpenGL is not actually open source, it's an open standard. So my original point is null and void as is.

I believe my hate for Microsoft had blinded me, forgive me.
