One of the absolute worst things about the pandemic was the deluge of garbage articles about COVID, like the ones she's talking about. "Someone somewhere found a correlation of X with Y!!!" gets reported as if it were Nobel-worthy.
"Did it used to be different?" No, science reporting has always been garbage. But in the before times, the mainstream news still reported garbage, but there was less of it to report, and you could easily find quality reporting if you looked for it.
Now there are many more "experts" vying for press time, and the press is able to disseminate their garbage much more effectively.
