News Corp masthead accuses rival media outlets of "co-opting readers into group think"

On 3 January 2015 The Australian decided it was time to give its readers the chance to laugh at the editorial staff by accusing others of its own journalistic sins:

This may come as a surprise to @JohnQuiggin but we love a contest of ideas. And we’d love to see the same ethos alive at other media outlets. We’d take great delight if controversial, unorthodox views were to be found on a regular basis on, say, Fairfax websites or the ABC. Sadly, with few exceptions, the editorial policy appears to be more about co-opting readers into groupthink, the enemy of rigorous, informative and productive public debate. Memo to the ABC’s Mark Scott and Greg Hywood at Fairfax Media: Journalism is not sociology.
