A better way to think
So when "free market" ideals come up short, re-define the market? How convenient.
"Satellite internet access" is what they offer and "satellite internet customers" with no other reasonable alternative are the ones being milked --- but it's "better" not to think about that?
Even in the latter case, nothing is preventing others from entering that market.
Except for the fact that Starlink is heavily subsidized by government contracts.
