Sara Jean Underwood (playboy model) performs nude yoga. Is it indecent?

A video from playboy is causing a huge uproar among Indian Community. Playboy tried to sex up yoga by posting videos of Playboy model Sara Jean Underwood performing yoga nude. Sara Jean is an avid practitioner of yoga. This comes at a time when Anil Kapoor has got a role to play the role based on Hugh Hefner in Mission Impossible 4.

I am not sure why this is a such a big issue as sadhus perform yoga in semi-nude to nude conditions all the time. What do you think? Are hindu groups reacting too much?
