A new European law restricting what companies can do with people’s online data will protect nearly 1.9 billion Facebook users around the world - unless Facebook pushes through changes to shrink this number. Facebook members outside the US and Canada are governed by terms of service agreed with the company’s headquarters in Ireland. But starting next month, Facebook is planning to restrict this to only European users, meaning 1.5 billion members in Africa, Asia, Australia and Latin America will not fall under the European Union’s General Data Protection Regulation, which takes effect on May 25.
