Why is Ratan Tata protesting about privacy?

Ratan Tata, the Chairman of the Tata Group is, reportedly, planning to move the Supreme Court against publishing intercepts of his conversation with Niira Radia. The stated reason - private conversation not connected with the 2G scam should remain private.

In principle, there cannot be a disagreement with the argument. On the other hand, unless there is something in the conversation that would be of interest to the world at large, it can be assumed that it will not attract attention, even if made public - after all, there is voluminous data that is threatening to come out in Wikileaks, that is likely to attract a lot more public attention over the next few days. So what can be a reason?

Perhaps it lies in a report published many months ago in a little know hindi website. This report, which purports to be a confidential letter written by a taxman investigating the 2G case has some interesting comments. The relevant excerpts are in points 2 and 3 above.
