Don’t think anyone except Peter Thiel and Hasbro will argue that Monopoly is a good thing. ;-)
SpaceX has made the investments/innovation to better-serve the satellite internet market that already had players in it; HughesNet, Viasat, Iridium / Globalstar. Those were the price-gouging Oligopolist incumbents who Starlink is disrupting with a 10x better service for considerably cheaper.
Totally agree that SpaceX doubling the price from $10k/month to $20k looks really bad especially if they’re doing it to existing customers.
But the way I see this (as a non-private-jet-traveler) is: Starlink is doing a “Robin Hood” and making the Rich (who can all easily afford it) pay for the expansion of the service which will benefit all the rest of customers. And if the 0.01% decide to switch to an alternative supplier, that’s good for competition. So in a way it’s anti-monopolist. ;-)
