Hat tip to KVSarma for identifying this unholy alliance and appropriately coining the phrase FWB.
The rooted silence on the barkhagate scandal, stoic defense of A.Raja, denial of any existence of Nira Radia, all leads to one question why? Simple answer the cHindu NDTV alliance. Its akin to 'Honor among thieves'. NDTV is the media "Godfather" and has collected many chips and its collecting them by means of total blackout (barring few non-consequential discussions) into this issue. In all likelihood it will provide some information to the JPC or whatever committee and in return be promised some minor slap in the wrist (no impacts to Government advertising).
Alternative Theory by Pilid (Which I have shamelessly copied from the comments)
The alternative explanation for cHindu's silence is the involvement of senior DMK figures. Perhaps it is some of both. Also senior folks in The Hindu have themselves acted as "conduits of information"; in fact Malini Parthasarathy defended accused journos on twitter on this ground. So the sympathy is understandable not to mention accusations would have amounted to the pot calling the kettle black. Also, the censorship is not unusual for The Hindu; most other major media outlets have not carried the item either. So the explanation for silence may lie in their loyalty to the broader fraternity of powerbroker/journalists.
