Summary from the TLDR Data newsletter

Meta built PrivacyLib to enforce privacy rules at the moment data is accessed, replacing one-off integrations with shared controls that work across many systems. The key lesson is to normalize diverse data platforms into a small set of common operations, which makes policy enforcement reusable, scalable, and adaptable enough to extend from traditional infrastructure to AI agents.
