I am not saying "journalists only cover what advertisers will cover".
I am saying "journalist's standards are increasingly coming second to the generation of advertising revenue".
Once-reptutable media empires embed Outbrain widgets and generate fad-focused, celebrity-focused clickbait garbage because it makes them money. They are not doing this for Journalism's sake. They are doing it for revenue from advertisers. I understand that this is an ancient phenomenon (PG's "suits back in style" essay comes to mind), but I have observed the scale and shallowness of the phenomenon worsening as the coffers get lighter at the news orgs.
For that reason, I am arguing that the "meaningfulness" of the difference between advertisers and journalists appears to be waning.
