India has the largest population of English speaking folks anywhere in the developing world, I assume. That combined with the fact that it already has a base of IT workers trained in this sector. (after all, outsourcing some kind of jobs to India has become the norm, not the exception).

Also, this is hardly a political issue. As a developing country, India rightly has many more pressing issues to deal with and people here often tend to skew towards that. This tends to put these scamsters on the back burner and seldom, action takes place. I, myself, was almost taken in by such a scam where they almost beguiled me into sideloading a malicious apk. Despite this, I cannot do much since proving cybercrime is much tougher here(especially when someone just attempted it, but was not completely successful).
