No I am not mistaken... I have read quite a bit about the Bonobo over the years and that is why I noticed it. This is a very recent observation. I
will see if I can find a source.
ScienceDaily (Oct. 14, 2008) — Unlike the male-dominated societies of their chimpanzee relatives, bonobo society—in which females enjoy a higher social status than males—has a "make-love-not-war" kind of image. While chimpanzee males frequently band together to hunt and kill monkeys, the more peaceful bonobos were believed to restrict what meat they do eat to forest antelopes, squirrels, and rodents.
Not so, according to a study, reported in the October 14th issue of Current Biology, a Cell Press publication, that offers the first direct evidence of wild bonobos hunting and eating the young of other primate species....
... "These findings are particularly relevant for the discussion about male dominance and bonding, aggression and hunting—a domain that was thought to separate chimpanzees and bonobos," said Gottfried Hohmann of the Max-Planck-Institute for Evolutionary Anthropology. "In chimpanzees, male-dominance is associated with physical violence, hunting, and meat consumption. By inference, the lack of male dominance and physical violence is often used to explain the relative absence of hunting and meat eating in bonobos. Our observations suggest that, in contrast to previous assumptions, these behaviors may persist in societies with different social relations."
Bonobos live only in the lowland forest south of the river Congo, and, along with chimpanzees, they are humans' closest relatives. Bonobos are perhaps best known for their promiscuity: sexual acts both within and between the sexes are a common means of greeting, resolving conflicts, or reconciling after conflicts.
The researchers made the discovery that these free-loving primates also hunt and kill other primates while they were studying a bonobo population living in LuiKotale, Salonga National Park, in the Democratic Republic of Congo. They had been observing the bonobos there for the last five years, which is what made the new observations possible.
Although Hohmann's team did have prior evidence for monkey hunting by bonobos, it came exclusively from indirect studies of fresh fecal samples—one of which contained the digit of a black mangabey. Yet, in the absence of direct behavioral observations, it was not entirely clear whether the bonobos had hunted the mangabey themselves or had taken it from another predator.
The researchers have now seen three instances of successful hunts in which bonobos captured and ate their primate prey. In two other cases, the bonobo hunting attempts failed. The data from LuiKotale showed that both bonobo sexes play active roles in pursuing and hunting monkeys. The involvement of adult females in the hunts (which is not seen in chimps) may reflect social patterns such as alliance formation and cooperation among adult females, they said.

Was their goal to denigrate the Bonobo?I see it as a fuller picture of them... no society, no animal, no individual is an ideal and all too often the Bonobo have been portrayed that way.
I doubt that it was, though it is being used to do so
Contrary to popular belief, lemmings do not commit mass suicide by leaping off of cliffs into the sea. In fact, they are quite fond of staying alive.
One of our closest primate relatives, the bonobo's, has been shown to voluntarily share food, scientists report.
This sort of generous behaviour was previously thought by some to be an exclusively human trait.
But a team has carried out an experiment that revealed that bonobo's were more likely to choose to share their food than opt to dine alone.

Dr Brian Hare from Duke University, US, and Suzy Kwetuenda from Lola y Bonobo, a centre for orphaned bonobo’s in the Democratic Republic of Congo, gave a hungry bonobo’s access to a room with some food in it.
This room was adjacent to another two rooms, which the creature could easily see into. One of these rooms was empty while the other contained another bonobo.
The hungry primate could then choose to eat the food alone or unlock the door by removing a wooden peg and share his fare with the other bonobo.
Dr Hare wrote in Current Biology: "We found that the test subjects preferred to voluntarily open the recipient's door to allow them to share the highly desirable food that they could have easily eaten alone."
