Is your concern plagiarism? The writer does attribute some quotes to three other named writers including the one you refer to, thus bringing them to my attention. I do think it would have been very helpful if Ravi Shankar Rajan had provided links to the academic articles or previously published stuff so it would be clear to readers what is new in his contribution. As another response pointed out, it is more of a “heads up” or an abstract than any deeper analysis.
