We need professional journalists who will be able to control the judges. And this is only possible with ISU spending some money on their training.
Look, as a journalist myself I know what sport journalism usually look like. Except few - extremely few tbh - lucky men, sport journalist are rarely specialists. It's just quite impossible to make your living on one and only sport, unless it's something highly popular, like football. People who write about skating have hardly any systematic knowledge about figure skating, hence they are easily manipulated.
As for accreditation, not only is it helpful, I believe it's actually needed to create a professional environment during press conferences. What is happening now is a joke. There are almost no questions regarding the technique or training process - there's a lot of "what-did-you-feel-when-crowd-cheered-for-Carolina-and-not-for-you" stuff. And when there's a skater who wants to tell something, say, politically incorrect (Wagner's type) - there's no one, but NO ONE, to create a proper interview, yet there's plethora of volunteers ready to quote her words with no context given.
If ISU could regulate journalism, it would be right now, with merely a handful of journalists being knowledgeable AND unbiased.
Knowledge has nothing to do with control.
