The European Union has opened infringement proceedings against Elon Musk's social media platform X, previously known as Twitter. The proceedings will focus on X's compliance with its duties to counter the dissemination of illegal content in the EU, the effectiveness of the social media platform's steps to combat information manipulation, and its measures to increase transparency. The investigation will also address a suspected "deceptive design" of the X user interface, notably focusing on the platform's so-called blue checks. X says the blue ticks denote verified accounts that have an active subscription to X Premium service and meet certain eligibility requirements.
