They admit as much in the article, by stating that they want to strike a tone that is not too positive and not too depressing. It isn't a journalist's job to do either of those things. A charitable take is that they want to be honest without disillusioning kids. They want kids to feel included in understanding current events, without making the world seem utterly hopeless (and thus inflicting a nihilistic world view). An uncharitable take is that they are grooming activists. They don't want it to be too positive so kids feel an urge to right some wrong, and they don't want it too depressing so they think there's still some agency to be advocated for.
