Domestication does not have to be deliberate, nor does it need to provide an immediate benefit to the party doing the domestication [1]. This is probably a common misunderstanding of the process. Plus for a little more complexity, we can expect that these aspects (to be deliberate, to provide benefit) can be recognised and emphasized during the domestication process.
[1]. It may be unsettling for us egotistic humans, but the domestication process can be mutual to the extent that it causes Speciation in both parties.
I also believe that Lions that rest near gazelles is a different scenario. If the Lion becomes hungry, it will almost certainly chase the gazelle in the right circumstances. The article made it clear that the wolves are not attacking these primates.
Also, according to the following website, sharks to eat fish. However, it's logical to assume that like the lion, they won't always eat fish if they are full or there is no return of benefit,

This one is fascinating because logically, you'd assume the wolves would attack the primates at any opportunity. It will be fascinating to see if the relationship evolves into one where the wolves defend the primates. Another poster posted the dog taming article. Maybe, just maybe, this group of primates may domesticate these wolves with time.
