What you're saying, then, is that the revenue generated by the sharing of journalistic content is worthless to Facebook, and the media outlets are just wrong to think that Facebook should contribute.
And yet, you signed agreements with Australian media companies, including a major three-year agreement with News Corp Australia. If journalistic content is worthless to Facebook and doesn't generate any revenue, why did you wholeheartedly agree, if you'll allow me a touch of irony, to sign such agreements and reverse your decision to block access to content? If it's worthless to you and doesn't generate any revenue for Facebook, why, then, did you backtrack and sign these agreements?
