The case is set in September 2019, and the protagonist of the case is Sheryl Sandberg. The case opens with her contemplating the new ventures on which Facebook is embarking, such as its transformation into a mega-app, the launch of its Libra cryptocurrency and the roll-out of its dating site, so as to continue its growth and to fend off competition. More than 99 percent of Facebook's revenues come from advertising and, along with Alphabet's Google, it dominates the digital advertising space. However, Facebook and other big tech companies are coming under increasing attack from governments and civil society groups for this dominance. Antitrust investigations and possible break-ups of these big firms are being proposed. Sandberg is facing other challenges as well. Concerns about how Facebook uses data it gathers from its users have come to the forefront. It has fallen afoul of privacy laws in Europe and the United States and been subject to large fines. Facebook's role as a vehicle for propagating fake news has been under scrutiny. Elections in the United States have been impacted and civil unrest (with occasionally fatal results) has occurred in other countries. Libra itself is facing problems, as governments and regulators voice objections to its introduction, applying pressure on potential partners. In 2019, Facebook was the fifth most valuable company on the planet, with a market capitalization of $540 billion (behind Microsoft, Amazon, Apple, and Alphabet).
