this is SOP for when a newspaper gets subpoenaed and is nothing new... i mean, i understand that you are worried about you getting gagged like that because the DOJ can and does do that, but it's nothing new. the federal government has been doing this for a very long time.
what's really starting to worry me is that newspapers are allowing themselves to be gagged instead of shoving this right up the DOJ's rear end, and it would appear to me that they are cooperating just to get closer to those same officials.
