Legal challenges have emerged in São Paulo regarding the application of digital platform metrics and data usage. 

In October 2026, the political party Rede Sustentabilidade filed a lawsuit with the Supreme Federal Court to contest regulations in the “Sala do Futuro” program. The party argues that using metrics from platforms like Redação Paulista and Leia SP to evaluate educators compromises pedagogical autonomy and student data protection. Justice Dias Toffoli is currently reviewing the case.

In November 2026, a São Paulo court issued an injunction against Meta, prohibiting the company from using journalistic content to train its artificial intelligence systems without authorization. This ruling followed a lawsuit by major Brazilian media associations alleging an abuse of economic power. The court imposed a daily fine of R$ 1 million, capped at R$ 100 million, to ensure Meta does not restrict access to its platforms for media outlets in response to the decision.
