This would be why Orwell said to break his rules rather than write something insensible. I think they're best understood as a toolbox for spotting when people are telling us certain kinds of lies. The passive voice is a tool, but it's important to look at why the writer decided to change the camera angle to avoid looking at who actually did the thing.

We certainly don't need to care about the agency for every trivial matter, but we certainly should know when clever 'camera angles' are being used by the author to hide an agent in the shadows.
