I’m pretty sure they ran the numbers for potential profits and determined it’s a goldmine - in the long run. Maybe they’ll need to increase the lifespan of satellites. Their internal launch costs are pretty low already. Amazon wants to build it’s own constellation and is building new glen partially because they can’t get launch slots from SpaceX. I’m sure you can find some numbers to do some napkin math.

Theoretically they can serve the whole world with internet without requiring only minimal land based infrastructure. That is a gigantic market they can reach. And incredibly power to wield for such a psycho.
