The European Commission said it will “make sure” it receives money owed by Elon Musk’s X after the company was fined €120 million for failing to meet transparency rules.

The Commission on Friday said X has breached transparency and deceptive design obligations under the EU’s platforms regulation, the Digital Services Act, and issued the €120 million penalty.

The decision set off a cascade of accusations of censorship from U.S. officials, Musk and his supporters, with some suggesting the company should refuse to pay the fine.
