We have journalists entering the workforce who have a good chance of having never consumed or witnessed any real journalism in their entire life.
So many of publications we used to know and love employed a sufficient amount of _professional_ copywriters, fact checkers, editors and so forth.
Editors were happy to let journalists take their time on stories that might not pay off for several years knowing it would pay to get things right.
Now-a-days, unless you work at the NYT, Guardian, or other company with mega-bucks and a robust subscription program you will probably never see a fact-checker, photographer, copywriter, and your editor will be not much more than an assembly line manager who may or may not care about the quality of the journalism you produce. If they do care, the likely have no leverage over the moneyed-interests who own the company.
A lot of people these days are not willing to pay for good journalism because they've been tricked into thinking they get "just as good" for free, which they most obviously do not.
And when they "discover" that their free news is run by rank amateurs who don't actually care about journalism and produce the kinds of things the OP rails against, it often seems to fester into a complete denunciation of the entire enterprise.
In fact, it is my belief that this is actually the goal of many unscrupulous practitioners of crappy journalism.
They know they can bankroll and support a crappy "news site" with the left hand and with the right hand use that to slowly tear down the firms putting out rigorous journalism, giving actual facts to citizens which show their ideology and politicians are nothing more than kleptocratic idiots.
