How Iowa Flattened Literature?

This is an interesting article -- How Iowa Flattened Literature -- about the University of Iowa Writer's Workshop, though I'm taking it with a grain of salt. The subtitle is: "With CIA help, writers were enlisted to battle both Communism and eggheaded abstraction. The damage to writing lingers."

"Did the CIA fund creative writing in America? The idea seems like the invention of a creative writer. Yet once upon a time (1967, to be exact), Paul Engle received money from the Farfield Foundation to support international writing at the University of Iowa. The Farfield Foundation was not really a foundation; it was a CIA front that supported cultural operations, mostly in Europe, through an organization called the Congress for Cultural Freedom."
