US, UK and France dropped so many bombs on Lybia they ran out and Germany happily restocked them.[2]

You are also saying that they were not material in its success. I would argue that the revolutionary ground troops would have suffered more losses if Gaddafi had had air support but the revolution didn't. Nevermind the tanks and such destroyed by NATO via air strikes. Potentially enough to make the revolution fail.
Is that not material?
The airstrikes were absolutely crucial to the rebels victory, and no one with any idea of how the war progressed would try to claim otherwise.
Before the airstrikes qadaffis forces were overrunning the rebels and were well on their way to benghazi off the back of their armored corps and air superiority, it was the airstrikes that put a stop to that.
