ETS's attitude is daft and as the author says, it is a crystal-clear case of the emperor's new clothes. Any non-fiction writing, and that includes the test passages, should communicate clearly (including headlines etc), so that the reader can concentrate on understanding the actual content. Imagine getting a gift, and spending all your time fighting the packaging. You lose time and energy just fighting the packaging, when the real aim should be to get you to the gift (ie the passage's main ideas/thoughts) as quickly as possible.
The point may have been made before, but we all know that any fool can make something appear difficult by writing without headlines, long sentences, little or no punctuation etc. We've all had teachers like this, who make things needlessly complicated and difficult because they are terrible at communication.
I think ETS is just making a big fool out of everybody taking the test.,
