from the "assume ignorance before maliciousness" standpoint, a lot of the impression you speak of is just a fact of us humans reporting on the (perceived) more critical news, (perhaps also maybe the more profitable news) - but is more (in my opinion) a natural result of the news having limited time/bandwidth to report on a near-infinite content production source (the world)
A side effect (and the end result) is that we all end up having poor [Bayesian priors](https://en.m.wikipedia.org/wiki/Prior_probability) in our heads - this disproportionate reporting practice at large impacts our understanding of the world, as you describe. And I bet there's a feedback loop: the more skewed our model of the world, the more we will produce/consume skewed content.
I think this is not something you can ever truly do completely away with because of the many factors that it arises from, not limited to our psychological biases that tend us towards liking or interacting with certain form of content more than others... but certainly there should be more controls.
