The original article is from an Indian news site targeted at Indian business people. This is relevant to that audience if they are looking to hire local developers. The study is, not coincidentally, put out by an Indian company whose products are employee tests and certifications.

I'm not sure where race/national origin factors into this if all the participants are Indian. Perhaps you could point that out? I am vaguely aware of India's caste system but I don't see any mention of it in the original article.
