Facebook Inc’s battle with publishers and regulators around the world regarding how the social-media behemoth handles news is far from over after striking an agreement this week with an Australian government to pay for content.The agreement Facebook reached on Tuesday with Australia’s government to reinstate news content to its platform comes as political leaders elsewhere have pledged to increase scrutiny on tech giants, and as news outlets also plan to rev up pressure on the company to cut deals. The matter also raises questions regarding which publishers should get paid for news content and how much.Facebook’s deal with Australia gives it a path to avoid required payments to publishers for news content, so long as the company works toward reaching agreements with publishers on its own accord.
