Meta faces a landmark lawsuit in Oakland brought by four US states (California, Colorado, Kentucky, New Jersey) alleging the company deliberately designed addictive features in Facebook and Instagram to target children. The case is being compared to tobacco litigation in the 1990s and could set significant precedent. Meta faces potential damages up to $1.4 trillion, forced app changes, and major reputational damage; founder Zuckerberg is expected to testify. With thousands of similar lawsuits pending against Meta and other social media companies, this trial could spark a broader regulatory reckoning for the industry.
