While testifying in court, the Meta CEO said WhatsApp and Instagram probably wouldn’t have been successful on their own.

The trial between the US Federal Trade Commission and Meta began this week—and the future of the company is at stake. The FTC wants Meta to sell off two prized assets, Instagram and WhatsApp, arguing that it acquired them illegally to suppress competition.

The Meta chief executive testified in a landmark antitrust trial that it was business as usual when he bought rival apps. He denied he was trying to snuff out competitors.
