If you wanted to, and I know you're just playing devil's advocate, but if you wanted to sell secrets to another country, which he could have done and become extremely rich doing so, the last thing you would do is take those secrets and give them to journalists and ask journalists to publish them, because it makes those secrets worthless.
Je sais que vous jouez juste l'avocat du diable, mais si vous voulez vendre des secrets à un autre pays, ce que Snowden aurait pu faire, et devenir très riche, la dernière chose à faire serait de les communiquer à la presse, car ils perdraient toute leur valeur.
