Or perhaps, as is becoming pretty ubiquitous in tech: the people who communicate things don't have nearly as much understanding as the people who do them. It was not always this way, but it seems the communication department in an organization is becoming the dumping ground for people who flunked out of doing the hands-on hard work but for one reason or another, have some support to retain them.

Note: I'm not criticizing tech writing. Just what tech writing has become.
