That is not the job of local news stations to be a free advertiser of only the positive aspects of local businesses.
My closest theme park is Dollywood. My local news station has run some very positive, flattering stories about the park and its reputation over the years. But when something goes wrong that is newsworthy, they are doing no service to the public to sweep it under the rug, so they report on it.
The employee had to be flown to a nearby hospital, and the incident prompted TOSHA to visit the park.

Same with Six Flags Over Georgia, my 2nd closest park.
Local Atlanta news stations have given plenty of positive coverage surrounding the park over the years. New ride announcements, festivals, etc.
But back in the early 2000s there was a new coaster called Deja Vu which had its share of breakdowns and closures... and the Atlanta news stations reported on it. Never once hinting the park or ride was a threat to safety, just letting the public know of reoccurring issues.
News being news is nothing new.
