Other than the sat-to-sat communications (which starlink is also planning) is there any real difference between the product offerings? Seems like a reasonable theory.
Very different in the details. I commented above, but tldr: Starlink is suitable for high-bandwidth applications but requires a complicated, high-power antenna. Swarm is only suitable for very-low-bandwidth applications (IoT), but can get by with very simple hardware. They're not really competitors.
