"News" and large facets of "journalism" have now, unfortunately, become nothing more than propoganda platforms filled with opinionated narratives to paint stories. Even when they're not, they often use selection bias to choose what they do and don't report on to tote some agenda.

Part of it is due to monetary incentives of businesses that now own the media outlets. Part of it is due to what the general public has interest in and will pay for.

Like pretty much all professions, it's also become far more demanding to be a good journalist or investigative journalist due to how many stories reported on require more specialized knowledge to understand and portray correctly. The bar used to be lower and a journalist could better grasp a situation or understanding. Now, with a lot of technology and science, you pretty much need a pretty deep and well rounded background to properly understand and address issues. The general bar of education has risen, including that of deceitful people, which places even higher demands on journalists to put them in check.

Could dig further into the point but the moral of the story is that the bar is raising to a point where misinformation and disinformation have an edge due to the sheer volume of information, lack of ability for any one person to have enough understanding, and incentives to be deceitful. That means the barrier to entry cost to dig out deceit has often become too high. I'm surprised we see much of any interesting investigative journalism anymore aside from uncovering some of the more obvious and massive schemes. Forget catching clever and sophisticated deceit, you need whistle-blowers for this.
