Network metadata became a significant topic in Brazil and globally following privacy concerns and NSA surveillance revelations. The term gained legal importance with Brazil's Lei Geral de Proteção de Dados (LGPD) and Marco Civil da Internet, which regulate how telecommunications companies and internet providers handle such data. Privacy advocates in both Brazil and the USA emphasize that even without content access, metadata can reveal intimate details about people's lives and associations.
