This story is getting a lot of play, seems like someone in the defense industry is pushing it hard.
Giving Starlink away for free as a humanitarian effort for the people of Ukraine makes a lot of sense, it's the right thing to do and good PR for Space X.
Using Starlink for military operations also makes a lot of sense, if you need it, they are building out "Starshield" services for just that purpose but it's not what the current network was designed for and it's hard to get the appropriate licenses in a war zone.
As for asking for someone to pay for the service: nobody is giving away military hardware for free, it's all on lend-lease agreements that Ukraine will eventually have to repay over time (the UK only recently finished paying their WWII bills to the US on similar agreements).
We know that DoD is paying for Starlink service in Ukraine, but there are no public details of the contract. Not sure how paying for a service is a subsidy.
"Opposing Autocracy" is an interesting choice of words, since everyone who's up in arms about this is implying that the government should force a private company to participate in any war on whatever terms they dictate. Freedom isn't easy, sometimes people and companies do stuff you don't like, but I we want a working democracy you have to give them that liberty or else loose your own eventually.
So does this mean that Elon thinks Starlink is responsible for whatever its internet access is used for? If Starlink can manipulate their service to inhibit war time activities, why wouldn't they be responsible for not shutting off access to people or groups facilitating crimes, such as distributing CSAM or drugs? Seems like Elon is admitting that Starlink does have the capability.
