I don't think this deserved to be downvoted. Foreign analysis of a local phenomenon always has a slant. It can't be avoided.
Explication of local culture in a foreign language for the benefit of foreigners will also have a slant. But it will be a very different slant, and it's a lot more accessible than the native materials. If the goal is "deep insight into how India works [today]", then Being Different is probably a pretty valuable thing to read even if the scholarship is shoddy. (On which question I have no opinion whatever.)
I think when the comment said basically "[I have no exposure to or experience with the course you're referring to but let's assume it's biased]", it attracts downvotes. This isn't "foreign analysis", in context it's just a proudly uninformed opinion.
I'm quite skeptical that any kind of deep insight can come from reading a prototypical Bharat Tyagi[0]. Reading Swami Vivekananda or even Gandhi would be a far better use of time.
