"This is not a personal issue. This is ultimately a sad saga of what I believe is a mixture of incompetence, political naiveté, conscious or subconscious political pressure and ultimately, I believe, a lack of courage of broadcasters when they are faced with the complexity of the Middle East issue and the intense emotions, fears and aggression it generates."

Ilan Ziv

Apart from "lack of courage" this is a misdiagnosis. The people who made the decision to shelve the film are not politically naive, no more incompetent than their industrial competitors, and quite aware of the complexities of Middle East politics.
The people who bought the film could be accused of naivete, if they honestly believed that the BBC would show a film that questioned the zionists' occupation of another nation's land.
