Journalist heroes must be convicted, brave and honest, but they do not need to be OPSEC experts. People who spend all day reading about PGP, and people who decide to risk retaliation by publicizing documents that have come to them, are both minority groups that rarely overlap (because then you'd have to have two unlikely traits, which is a lot less likely than having one.)
You might want to alter your word choice a bit. As an American, “must be convicted” reads as “must be found guilty in court”, which I’m pretty sure isn’t what you meant. Even changing the order to “brave, convicted and honest” would help — putting the ambiguous item in the middle of the list helps to clarify which meaning you intended.
They might need to be OPSEC experts if they want to publish two articles, but to publish one they do not. I'm pointing out that civic motivation and technical knowledge aren't correlated.
