That's absolutely true. I understand that this particular piece is a step beyond that: a 'must run' segment that was mandated by corporate (something for which Sinclair has form).
That's the thing: I don't know if anyone ever established that it's a "must run". I've only ever seen this clip as evidence for it, so I'm still not sure that it's not entirely conjecture.
Lots of people like to point to AP or Reuters as examples of copy-paste news programming, but that ignores the primary difference: affiliates select which AP or Reuters stories they want to air and/or publish.
Others compare TV networks like ABC or CBS requiring shows to be aired at certain times, but none of the networks mandate local news coverage like Sinclair does.
