“They should donate it to Ukraine in lieu of an equivalent amount of actual money”
Thats what most US aid to Ukraine IS.
That said, the problems with these things are such that they amount to negative military value.
Giving it to Ukraine will be a great idea.
There will be no maintenance costs on it, because it will be sunk within a week of arriving in the Black Sea
All the more reason to shovel it off on someone else.

Ok, then give it to Russia :)
