Yeah, this is pretty horrible. Many applications try to be friendly and show a Hindi webpage just because you are in India or in particular, Northern India. India has around 25 major languages, and people from all over the country work in all parts of the country, so assuming Hindi as the default language for every person currently present in North India is not correct.

Language is a sensitive issue in several parts of India. Why not be polite and ask the user for language preference first?
