Musk won acclaim earlier this year after intervening to bring internet services to Ukraine during the Russian invasion. However, he became embroiled in a spat with Ukrainian leaders last week after calling publicly for a negotiated settlement to end the war in the country, which would include allowing Russia to keep Crimea.
In response to a tweet quoting a Ukrainian diplomat who told Musk last week to "fuck off" following his proposed peace settlement, the US-based entrepreneur appeared to threaten to pull the service in the country, writing earlier this week: "We're just following his recommendation".
Musk had complained that his company was spending millions to "create, launch, maintain & replenish satellites & ground stations & pay telcos for access to internet via gateways." He added that the company had also "had to defend against cyber attacks & jamming, which are getting harder."
On Saturday, he responded to a comment on Twitter saying that "no good deed goes unpunished", writing: "Even so, we should still do good deeds".
The Pentagon declined to comment on the news.
The Financial Times previously revealed that some Starlink terminals used by Ukraine's military had stopped working in areas recently liberated from Russian occupation, raising questions about whether the company was blocking the service to some parts of the front lines.
