For people that are against IBOC and pray for its early demise, I'm sure you will be able to find examples of interference. Because of the vaugaries of skywave reception, WLW, WOR and WGN occasionally have a difficult time in Western PA without IBOC. But I'm sure that wouldn't matter to the anti-IBOC people.
