If I would change something it would be a higher priority in data privacy and security. While meta has revolutionized social network and communication technologies it has also received criticism regarding the handling of user data.
Implementing more transparency on how the user data is handled, privacy by design. Giving the user more control over their use data including, exporting or deleting their data. Implementing security controls to prevent breaches and unauthorized access like threat monitoring, advanced security systems and end to end encryption.
By focusing on these areas Meta will continue building awesome things while fostering greater trust among its users.
