First example that comes to mind is Starlinks for Ukraine.

Also, it's not like Ukraine or even Poland has to pay, the can pay if they want, they can also not pay if they want. It's entirely elective. They can stop using any time they want. I heard that Google has a Starlink replacement in the works that is super awesome and I also heard that while Europe has completely killed itself with regulation they are entirely willing to buy things made by China which has absolutely no regulation.

even if they pay, he can supply it if he wants, or he can cut them off if it threatens to inconvenience Russia.
