Facebook faces challenges regarding its business model and privacy policies. While it has widespread popularity due to e-commerce technologies that allow social networking and targeted advertising, weaknesses include violating user privacy through opt-out policies and retaining deactivated account information. Management failed to understand user privacy concerns when launching services like Beacon that shared user information without consent. The company also struggled to balance monetizing user data for advertisers while maintaining user trust and control over personal information sharing. While Facebook has potential through its large user base and targeted advertising, questions remain over whether it can sustain revenue from advertising or if users will reduce engagement and sharing due to privacy issues.
