I don't think any decent person can even repeat the dialogues. Anyone who sees the film will think that the widows in Brindavan are prostituting. I think it is a generalisation of the tapasya of the thousands of widows who may have nothing to do with prostitution. In India, let us assume that law permits many things. The government can permit what it wants to, but society need not do so.
Society can say, nothing doing.
These people are not making the film for a noble cause or to change society. They are commercialising an issue to make profits. That is irrelevant. The society sustains itself. The society feeds the poor, it is not the government which does so.
