I'm South Indian as well, and I didn't pick up on any condescension. If anything, the writer went out of her way to present the views of obvious scammers as fairly as she could.
I mentioned I was South Indian to emphasise my bias towards such a tone.
But as I have acknowledged in my above comments, I may have looked at the article through biased eyes, but I still think I'm right in my assumption about this author's tone.
