Part of Starlink's value proposition is the promise of lower latency internet communication. Information travels roughly half as fast through metal, atmosphere, and fiber optic cable as it does through a vacuum. By relaying data through the satellite network, data can be sent tens of milliseconds faster from one side of the Earth to the other than existing technology. That's worth a lot of money to a lot of businesses.

The current starlink satellites lack communications lasers, and so they can't relay data between satellites. The latency is therefore no better than current technology. SpaceX needs to launch a new version of satellites with communications lasers in order to reach the full advertised potential. The new satellites are bigger than the current ones, though, and their current Falcon 9 rocket can't economically launch them in volume. So, they're doubling down on using the fully reusable Starship platform to launch them. The fear of bankruptcy is due to the fact that Starship doesn't actually work reliably yet. They need to get Starship working in the next year. Otherwise, they'll risk running out of money.
