That's based on forecasts and not real numbers (because SpaceX is a private company), but it's a good point.

They've announced that they had 1 million users in December. It's likely that ARPU is over $1000/user.

Assuming they are adding faster than losing.

I think we can agree that starlink is growing and will continue to be a bigger share of their revenue. That doesn’t negate my point, though.
