Putin would've won the war in a week or two if it wasn't for Elon Musk.
It's well worth reading the whole article, I've copied a link to it.

An hour before Russia launched its invasion of Ukraine on Feb. 24, 2022, it used a massive malware attack to disable the routers of the American satellite company Viasat that provided communications to the country. The command system of the Ukrainian military was crippled, making it almost impossible to mount a defense. Top Ukrainian officials frantically appealed to SpaceX founder Elon Musk for help, and the deputy prime minister, Mykhailo Fedorov, used Twitter to urge him to send Ukraine terminals so it could use the satellite system that the company had built. “We ask you to provide Ukraine with Starlink stations,”
he wrote.
"
Musk agreed. Two days later, 500 Starlink terminals arrived in Ukraine. “We have the U.S. military looking to help us with transport, State has offered humanitarian flights and some compensation,” Gwynne Shotwell, Musk’s president at SpaceX, emailed him. “Folks are rallying for sure!”
"Every day that week, Musk held regular meetings with the Starlink engineers. Unlike every other satellite service, they were able to find ways to defeat Russian jamming. By March 6, the company was providing voice connections for a Ukrainian special operations brigade. Starlink kits were also used to connect the Ukrainian military to the U.S. Joint Special Operations Command and to get Ukrainian television broadcasts back up. Within days, 6,000 more terminals and dishes were shipped, and by July there were 15,000 Starlink terminals operating in Ukraine."
