Liberdade de expressão e responsabilidade das plataformas digitais: o caso X (antigo Twitter) e a decisão do STF

Abstract

This monograph aims to analyze freedom of expression, hate speech, and the obligation to comply with Brazilian judicial decisions, using the controversial decision by Minister Alexandre de Moraes of the Supreme Federal Court (STF), which ordered the suspension of the X (formerly Twitter) platform’s activities in Brazil, as a case study. The research explores the necessity of respecting national legal sovereignty, in a context shaped by the growing influence of digital platforms in contemporary society and the challenges they pose to the enforcement of national laws. The decision to suspend X sparked an intense debate on the limits of freedom of expression and the role of digital platforms in data protection and combating misinformation - key issues that this study addresses. To achieve this, the research analyzes the judicial decision in light of the Brazilian Internet Civil Framework, the General Data Protection Law (LGPD), and the constitutional principles governing freedom of expression and national sovereignty. The goal is to understand the challenges and contradictions inherent in content moderation on digital platforms, the responsibility of internet companies to comply with Brazilian laws, and the guarantee of the effectiveness of judicial decisions in the digital environment. By analyzing the X case, this study seeks to contribute to the ongoing debate on the regulation of digital platforms and the protection of national legal sovereignty in the internet age, where borders become increasingly blurred and challenges to the application of the law multiply.
