We've had satellite telecommunications for many decades now. What makes Starlink so unique is that it's a Low Earth Orbit constellation, which drastically lowers latency and improves bandwidth; two things that usually make satellite connections sub-par compared to almost any other option. But to get global coverage at such low altitude you need a massive constellation of thousands of birds - which is why SpaceX was the first to build one, as their launch costs are lower by an order of magnitude due to having reusable rockets. To make any kind of competitor to Starlink/Starshield, you'll need a re-usable rocket of your own, or to pay SpaceX to launch them - and they may well decline to orbit the birds of a competitor. This is a unique capability that only the United States has ownership of. The idea that anyone can just "replace" Starlink is born of profound stupidity.
