To avoid over-assertion:
(vii) Don't delete attributions (30, 34). I have argued that copy editors should retain source and agency attributions.

This reminds listeners that the news has a specific, human source . .It is a report, just one version of events. Agency attributions are less obviously vital, but in my view still important. If agency attributions were always retained, audiences would have the chance to recognize two facts: that most of the world's news originates in the Big Four agencies, and that most overseas news enters New Zealand on a single wire. In many other countries, both news sources and outlets are more diverse. In New Zealand, the public can read a story in the morning paper, hear a parallel account on radio, and watch it again on evening television news. Multiple reinforcement from apparently independent outlets makes the story and its details seem unassailably authoritative. But many witnesses do not make one truth when they are all second-hand accounts based on a lone wire containing unknown errors of fact and interpretation. Attributing a story to its source agency would at least make this situation explicit.
