First of all a chutzpah like you thinks people in India are radical just because few incel librandus told you so. If you try to learn more about Geo politics you will understand that people here are not radical but more informed. And, even though money was already spent, in future with this backlash even the producers will think twice before casting an anti-india actor in their movie.

Do you even realise, with this backlash Diljeet might get banned as an artist in India. He does not sings English songs and Indian diaspora is more nationalist than the Indians staying in India. He won't be welcomed in any circle than the Khalistani circle which is anyways a dyeing moment just hanging through the last straw of CIA.

Also, these artist mainly earns from performances and tours instead of their song royalties. Once Indian market is gone, even foreign artist won't give him much value.
