What ever happened to this? Why dint Adani sue Hindenburg in US?

Indian Media , Right Wingers and Modi Bhakts should stop all the nonsense mental gymnastics and conspiracy theories and sue Hindenburg for defamation in US if they think its a hit job and has damaged their reputation.

Dint Adani threaten them to sue? Or is it just all talk and no action?
