U.S. billionaire Elon Musk has agreed to sell a portion of Starlink assets to the U.S. Department of Defense, removing himself from decision-making regarding geofencing Ukraine's access to the satellite internet service, Musk's biographer Walter Isaacson told The Washington Post on Sept. 13.

Isaacson describe the move as a "right outcome."

"What he did, which I think is the right outcome, is he decided to sell and give total control of a certain amount of Starlink equipment, Starlink services to the U.S. military, so that he no longer controls the geofencing, he no longer controls the terms of use," said Isaacson.

He also suggested that the Ukrainian military has only limited access to Starlink connectivity in eastern Ukraine, in addition to Crimea.

"Musk had not enabled it [Starlink] in Crimea and kept that a secret …; they can't figure out because Musk also decides not to enable it in parts of eastern Ukraine because he doesn't want it to be used for offensive purposes," the biographer adds.
