Facebook held an open meeting at 10AM Tuesday morning in Menlo Park (4AM Wednesday AEDT). The whole company was invited to gather and ask questions about the recent - and rather furious - scandal around how Cambridge Analytica, a private data company hired by the Trump campaign that acquired and leveraged information on over 50 million Facebook users. Facebook general counsel Paul Grewal was at the meeting to provide some answers. Mark Zuckerberg was not.
