Brazil's telecommunications regulator threatened sanctions against Elon Musk's satellite internet firm Starlink, as a public confrontation with the billionaire escalates over the country's decision to block his social media company X. Last week, Brazil's supreme court ordered a nationwide suspension of X for not appointing a legal representative by a court-mandated deadline, in line with the country's laws. Anatel, Brazil's telecommunications regulator, has instructed internet providers to block access to X following the court order. Artur Coimbra, a commissioner at Anatel, told Reuters that Starlink is the only company that has told the regulator that it would not comply with the court decision. CNBC has reached out to Anatel and SpaceX, which runs Starlink, for comment.
