Difficult. If Haaretz would break the deal with the government they would never get any inside information, but if they stick to the deal they would commit the biggest crime against free journalism... Anyway, the Israeli journalists that are for free press will do like they always did± secretly tell their journalist friends in the foreign press (NY times, Guardian) who publish the story and then it's in the open and haaretz can quote the foreign press.... In this day and age, Bibi and his ilk are deluded they can keep things quiet.
