I would assume many high profile publishers would be concerned in getting the facts right. Especially if working with freelancers, there might be interest to see in more detail the creative process. Just a random example for Google about a case, where journalist had been faking things [1].

Maybe there would be also use in areas like technical writing, rules and regulations or contracts. Having errors in these can actually have big financial consequences.
