I'm not the person you replied to, but this stood out to me:

"And so (sorry, Orwell, but my guilt is too great to avoid the passive voice) certain strategies have evolved."

This sentence isn't in the passive voice. ("Have been evolved" would be.) I would expect a good editor to be a grammar expert and catch that error.

Agreed, syntactically. However, it is passive in that the strategies aren't actually the actors. The word _evolved_ has a general passive use while actually retaining the active voice syntactically. The actual passive voice version you gave is not normal usage. The author is the actor who has developed strategies, but he is dodging the responsibility by making the strategies be the subject of the sentence and leaving himself out.

The "passive voice" is a term with a technical meaning in grammar. "Evolved" used intransitively doesn't qualify. This is the kind of thing an ordinary person mostly shouldn't need to care about, but if you're going to reach for the cutesy editor joke...
