Starlink revenue is estimated at $30 billion / year.
I don't believe it.
Apparently, it is 3% of global telecommunications revenue, which does not sounds unreasonable to me.
Existing telecommunication corporations are not going to just give them the share of the market, even 1% or it, just because the launched a few satellites. They all have their own satellites, and plenty of them.
And revenue is not profit, btw.
