There's a lot more when it comes to Starlink:
- The obvious political point: that ISP is subject to laws in a country that is testing its legal framework and diplomacy in new (some may say unpredictable) ways.
- The first rule of public funding is that the money goes back to the public. Roughly all (if not all) of the jobs for Starlink go to the US, whereas fiber installation in France employs French people.
- Paying for Starlink is a terrible investment because the entire constellation is disposable. Every satellite will burn up in roughly 5 years and the whole network would go dead without more launches. Fiber, once installed, is at least serviceable.
- Another political point, but the only company that can launch replacements economically is also subject to laws in that same country.
Starlink hands an awesome amount of semi-soft power to whatever country controls it. It doesn't really matter what country that is: it's a huge strategic liability to anyone who doesn't hold the keys. Until there's at least another player in the game I'd expect a lot of countries to be wary.
Ironically, that could mean Starlink/SpaceX really needs a competitor before it can become a universal solution.
