You’d think that SpaceX is highly profitable and is using those
profits to expand into the satellite Internet business. But actually
there is debate whether SpaceX is profitable without accounting
tricks, and even if it is profitable, the margins are very thin.
Reportedly the geostationary launch business is softening, and SpaceX
is actually looking to Starlink for profits. No doubt it helps if
you can launch your own satellites, maybe even having them ride along
while you get paid to launch stuff for paying customers. But this
sounds like a pretty risky venture, paid for with borrowed money. If
it wasn’t risky, it wouldn’t be Elon, right?

I would suspect they are going to have hundreds of earth stations as
opposed to one or two earth stations that legacy platforms have. Up
to the bird, maybe across one or two birds, and back down to the
fiber-fed earth stations. I've seen the numbers, but I forgot the
numbers. It's real bandwidth at each one.

What kind of bandwidth capacity could each satellite have at any
given point?
What is the usable bandwidth of their system? Who makes a radio that
big to carry/transmit such capacity or is it an
aggregate of small radio's?

I think one factor advocacy groups and govt critters need to keep in
mind is that instead of robust competition, what could occur is
“disruptive” pricing, having the effect of discouraging or

game in town. And if it turns out to be unreliable, or not to have
enough capacity, or their speeds are actually best effort, or their
satellites start dropping out of the sky, or whatever, people can’t
switch back to their old provider. Like being dissatisfied with
online stores and assuming you can always switch back to the old
brick and mortar store, from Uber and Lyft back to taxis and limos.
Sorry, they don’t exist anymore.
This is unlikely to happen in big cities, I doubt Comcast will go
bankrupt because of Starlink. But to just assume there will be lots
of choices out in the middle of nowhere driving the price down
without any of them turning off the lights, seems a little naïve.
And to assume big megacorps like SpaceX, Amazon, Googe, Facebook,
etc. would never price below cost to be “disruptive” also seems naïve.

Sure. But after the clouds, geostationary still needs to go another
23,000 miles. LEO only has to go a few hundred.
