Kudos to the author for doing a bunch of good data analysis and investigation. Pro or con against the result it gives a better context in which to read it rather than a simple headline that you can use in the next argument you have. IMHO while the author touches on Git/OpenSource contributions as part of higher salaries. What it also touches on is people who are working on improving their skills and contributing understanding which is a different individual than somebody who just takes surveys and works at a big company.
