DID THE FOO FIGHTERS RIP OF AN OZZY GUITAR RIFF?

Ozzy Osbourne guitarist Zakk Wylde was asked  about the similarities between Foo Fighters’ 2002 song “All My Life” and Osbourne’s 1991 song “Desire”Zakk wrote the riff on that song, and he  had this to say about the likeness:

“There’s nothing wrong with that. I mean, they’ve heard it and it was like, ‘Dude, that riff, why would you do something like that?’ I mean, Dave’s song is completely different as far as the melody goes and everything he does with it.”

But the similarity is noticeable. Until someone points it out, you prob never noticed. 

Do you think is a simple coincidence or was Dave Grohl and the Foo's influenced/inspired by Ozzy and Zakk's riff. When is it  INSPIRATION and when is it STEALING?
