I agree but politics trumps both. Ecuador may not want to get into an extradition battle with the U.S. that could effect their trade.
Now
there's a great argument to prove what legally-principled, high-minded sonsabitches we are when our sovereign authority wants something changed that another sovereign authority did within its international legal rights. I'm sure it'll be played back to us the next time we're over a barrel and try to make a humanitarian appeal to get our way on something, or grant asylum to a Russian or Chinese activist.
Seriously, getting him back is just an issue of retribution, whatever cats he had are completely out of the bag and have been for awhile. There's nothing that's going to actually be improved by getting him back. The only remaining purposes to putting the
habeus grabbus on him now are to stop the PR bleeding for Obama and the NSA, and beat the crap out of him (In a legal sense). Fox and the rest of the MSM are focused on how shameful it is that he doesn't turn himself in, which frankly he'd have to be a total moron to do, since the DOJ will devote literally-limitless resources to imprisoning him for the rest of his life, with the press baying for his blood (On the right, for the national security issue, and on the left more for embarassing Obama) rather than even pretending to show a whole picture, and no resources to defend himself.
'Way too much is being made of this guy, he isn't actually important anymore, just another fugitive that better never set foot in the US again if he knows what's good for him.
