What do the Indian people who live in America do? Do they wipe with their hand or toilet paper? I'm gonna guess they bypass shitty fingers and reach for the Charmin.
My Indian friends all use paper and never make an issue of it, the old people do still watch and will yell at people if they use their left hand, even if everyone is abides by western bathroom habits.
I have have a feeling that a lot of it is class/caste based too, that Chinasmack article caused a lot of discussion amongst Indians, most of the expat Indians were like "I love India, but it's horribly dirty", etc....
