To the business world, open source is just a business calculation and HR really doesn't care about it except when it's useful as a recruiting tool. The same is true of hiring decisions and open education. Degrees from well known universities are part of a cost/benefit/cover-your-ass strategy in hiring decisions so when open education has proven itself to the degree that open source software has, then it will be as widely accepted.

The business world uses microsoft windows and office. Couldn't care less about open source.
