However, NOYB pointed out that the European Court of Justice had previously rejected the legitimate interest argument when Meta tried to make a similar case for using all personal data for advertising. Following this, the Irish Data Protection Commission delayed the launch of Meta's AI model in June to investigate Meta's data collection practices. Meta said that it was "disappointed" in the EU's regulatory action and called it a "step backwards for European innovation, competition in AI development and further delays bringing the benefits of AI to people in Europe." The Mark Zuckerberg-owned company also argued that companies like Google and OpenAI rely on European user data to train their AI models, implying that it's common practice. Meta also stated that its 'opt-out' approach was "more transparent and offers easier controls than many of our industry counterparts already training their models on similar publicly available information."
