The richest man in the world, Elon Musk, said on Friday in a message published on Twitter that SpaceX cannot “indefinitely” finance Starlink internet service in Ukraine, News.ro reports.

“SpaceX is not asking for past costs, but it also cannot indefinitely fund the existing system and send several thousand additional terminals with data usage 100 times that of the average household. This is unreasonable,” he writes.

The CEO of SpaceX equipped Ukraine with the Starlink system in the first days of the Russian war at the request of the Deputy Prime Minister of Ukraine Mykhailo Fedorov.

This technology plays an important role for the Ukrainian military, which has used it both for communication and for controlling drones and artillery.

The Financial Times revealed last Friday the system failures reported by Ukrainian forces in areas recaptured from the Russian army.

The incident comes just days after Musk proposed a peace plan in Ukraine on Twitter, leading to confrontations with several Ukrainian officials.

“To hell with my diplomatic answer,” answered Ukrainian Ambassador to Germany Andrii Melnyk.

According to CNN, last month SpaceX sent a letter to the Pentagon in which it warned the US administration that the company will not be able to continue funding the Starlink service in Ukraine indefinitely and that it may be suspended if the US military does not pay several tens of millions of dollars a month.

The CEO of Tesla wrote on social networks that the installation of Starlink cost 80 million dollars, and by the end of the year the bill will exceed 100 million dollars.

The richest man in the world responded to a tweet in which he quoted the words of Andrii Melnyk “fuck you” that “we do nothing but follow his recommendations.”
