I was curious so I googled. The ban was lifted. The ban was put into place because people were broadcasting provocative and violent videos showing torture and cutting throats of cows (sacred to Hindus in neighbouring Indian states). Eg: https://www.youtube.com/watch?v=dzSBk6n1olU

As an Indian I would say this action by the government was both very unfortunate and very un-pragmatic.

However, it would be worthwhile to note that it was the elected and relatively autonomous state government of Jammu and Kashmir which enforced this ban.

It seems there was a sense of panic in the J&K government because of the recent rise in terrorist attacks, and waving of ISIS flags each Friday in Srinagar. So they thought that some elements - of all shades/religions - might use this occasion to incite communal tensions between the Hindu and Muslim residents of state. Not a reason valid enough IMHO, but worth to note.

Anyways they would be held accountable for this in the next elections, so let's hope it never happens again.
