The other companies did not provide a reason for their departure.
X, formerly Twitter, is owned by tech billionaire Musk. He has been criticized for publicly endorsing European far-right parties, and he serves as key adviser to U.S. President Donald Trump.
Belgian far-right party Vlaams Belang condemned the decision. Flemish parliamentarian Chris Janssens of Vlaams Belang said that the move “cannot be seen in isolation from the figure of Elon Musk.”
“Banning communication channels because the owner is not to their liking is not good governance,” said Janssens.
Musk’s X has also been under investigation by the European Commission over its compliance with the bloc’s flagship content moderation law, the Digital Services Act (DSA).
Under Trump, Musk is heading the so-called Department of Government Efficiency (DOGE), which has slashed federal agencies and cut international aid.
