Some very rough math. $16 billion in EBITDA with 9million customers. This translates to about $1800 average annual subscription. Per month this is $150.
That is I think Starlink's target customers are ISP deprived. I asked Gemini estimate the size of that market. It said about 10 million in the US and over a 1 billion worldwide. I assume the Elon is pushing the 1 billion number. The problem I see is that outside the US, not everyone can pay $165 per month for internet.
I don't mean this as a gotcha or anything. I imagine rockets are a capital-intensive business. So are datacenters.
