You would balance the public interest in the revelation against the possible harm. Best guess is they see the harm as minor as 1. It is not revealed who Thiel was informing on and 2. To the extent a target could guess, Thiel is very well equipped to protect himself from physical threats. Further, it doesn’t seem Johnson is implying physical retribution, it seems more like (arguably) he’s trying to expose what he sees as some sort of ideological hypocrisy. So any harm would be reputational (and debatable) if that’s the case. Many sources for news articles act out of self interest, whether to benefit themselves or hurt an enemy, so that would not be inherently disqualifying. (Not endorsing the presumed logic just describing it.)
