It seems like the issue is a lack of competition, if I don't like what Sinclair is saying I can not watch it, but if they own all the stations then I don't have that choice. The FCC did all this while everyone was distracted with net neutrality, so even if it came up again there the FCC knows how to distract people already. I'm just not sure what I as a viewer/voter can do about except wait for the next election, and even then, there's no guarantee that the candidate who wins is going to do anything about it.
But... looking at the list of stations Sinclair owns[0]... where are the markets that they control all the stations, defined as ABC+NBC+FOX+CBS? I honestly don't see any. Is this more of a concern if they do manage to get all of these, or if the merger with Tribune Media goes through?
