Today, Frances Haugen, a former Facebook product manager, testified before US lawmakers as a whistleblower. She was armed with company documents to back her claim that Facebook and Instagram can be addictive and harmful to children. Part of her message: Facebook's CEO Mark Zuckerberg has always been aware of the dangers, choosing to put astronomical profits over the welfare of people. To understand this, Haugen described a business model designed to ensure that content gets our attention, and keeps us coming back. The more engagement, the more advertising revenue. Profits are pushed ever higher, bonuses for Facebook executives get bigger and bigger. This is part of Haugen's opening statement delivered earlier today.
