Except the person who leaks, if his/her identity is known, will be prosecuted for sharing trade secrets - and given there's trillion-dollar companies behind TTP, s/he will spend the rest of their life, if they are arrested, either in lawsuits, prison, or just disappearing. Snowden and Assange are both effectively banished from any country that has an extradition policy with the US, and even where they live now their location has to be kept secret - if they weren't as public figures as they are (and in Assange's case, locked up in an embassy), I'm sure they would've 'disappeared' a while ago, regardless of where they were hiding.
