On April 4th, according to Wall Street news reports, the European Union plans to impose a heavy penalty of more than 1 billion US dollars on Musk's social platform X, because X is suspected of violating the Digital Services Act and failing to effectively supervise the platform for misinformation and illegal content. Regulators are also advancing the second investigation against X, and may include the revenue of Musk's other private companies in the fine base, and the final fine scale may far exceed expectations. Analysts believe that the recent supervision of technology companies by the European Union may be one of the reasons why Trump announced high tariffs on the European Union this week. The New York Times quoted four people familiar with the matter as saying that European Union regulators are preparing to impose heavy fines on Musk's social platform X for allegedly violating the Digital Services Act (DSA) provisions on cracking down on illegal content and misinformation. The penalty is expected to be officially announced this summer, or become the first official penalty issued by the European Union under the law.
