This puts developers in companies that commit to open source projects like Chromium to be at a significant advantage to those developing proprietary software. I understand where the author is coming from, but this is unfair for those who work on closed-source projects. Of course I have my own personal projects, but for most of them, I am not about release their source.
If the ability to demonstrate that they can write good code with concrete examples puts someone at an advantage over others, so be it.
