Well, right. Corporations internally work towards their diversity goals, which are sensibly based on the pipeline and aim to eliminate bias in hiring. That's why they don't want to publicize their numbers; they know people like the Bloomberg reporter who wrote this article will incorrectly try to measure their efforts against the total number of minorities in the US.

The hiring pipeline is discussed explicitly in the article, and comparison to national demographics is legitimate.

Comparing hiring to national demographics is not legitimate. You should compare hiring to national graduates with CS degrees, controlling for institution. That will tell you if there is discrimination in the hiring step. If you want to see if there is discrimination in entrance to CS programs, you go a step earlier, etc. And you keep walking back until you find the source of the discrepancy. Where do women get off the CS pipeline? Is it at the hiring filter? The college major filter? Somewhere in high school? Even earlier? It's disingenuous to place the blame for the entire pipeline at the feet of the entities at the very end. Somewhere there is a bias, but it isn't necessarily at the corporate level.
