Tails is a Linux distribution aimed at privacy and anonymity.
Debian, which is much better known and in much wider circulation than Tails generated weak SSH keys for two years. Yes, it was indeed very big news. When it was found. After two years.
Oh, and tin-foil-hat on: Do we know (actually know-know, not just assume, think, trust) that the weakness wasn't planted there?
Also, how do you know that Tor and Tails aren't infiltrated by the enemy (for any value of "enemy")?
Or parking up and walking past the bank next to the coffeeshop a few more minutes before entering the coffeeshop?
You have to be even more paranoid if you are on a short list of people with access to the information - they will pull up all of your movements, possibly check traffic cameras for your care movements, etc.
Long range Wi Fi just makes so much more sense.
Hell, even have it transcribed by a typist. Full air-gap. This whole leaking business needs to be turned into an SEO optimized translated wiki page.
* Use a Linux live CD on the "burner laptop" -- don't trust the preinstalled OS
* Change the MAC address of the Wifi used to connect at the internet cafe
* Use Tor, most easily via the Vidalia browser bundle
The author also does not mention that leaking documents can expose the whistleblower via watermarking and user information embedded in the file (most infamously in MS Word documents with versioning).
Edit: update formatting
