The problem is that they’re the single largest television broadcaster.
Headquartered in Hunt Valley, Maryland, the company is the largest television station operator in the United States by number of stations, and largest by total coverage; owning or operating a total of 193 stations across the country (233 after all currently proposed sales are approved) in over 100 markets (covering 40% of American households), many of which are located in the South and Midwest.
With the shift to the various 21st century streaming platforms, broadcast TV in its traditional form is rapidly becoming the bastion of the elderly. The average traditional broadcast news viewer is 50+[1] so very soon Sinclair will be dominating retirement homes everywhere in America. It's a demographic that will literally die out from under them, and seems like a poor long-term investment.
You may not be aware of this, but typically you don’t enter a nursing home at 50. Either way, Sinclair is also well into streaming services, which you could have discovered with even a cursory glance at their Wikipedia page. Of course, a huge number of people, especially people who vote, are in that same age bracket.
