WHO had made an unfounded guess and stated it as fact, and called a position with as much basis as they did (arguably even more, but still inconclusive) as misinformation because it disagreed with it. The appropriate approach would be to state "given current arguments, we are not sure whether it is airborne or not" instead of doubling down on their assumption/guess.
