So the idea would be to teach other chimps hundreds of miles away the same technique. Exactly how to teach them is a little tricky. Maybe the handful of groups that are used to people can be shown a model snare and how to break it, or possibly even shown a video similar to the one at the link, showing other chimps breaking snares. The other trick is getting juvenile female chimps to learn the technique, because males stay with the group they grow up with, while females disperse to new areas and can take their knowledge with them.
I don't know, maybe it's not feasible. But just the fact that we can consider teaching chimps appropriate technology in a manner resembling the way we think human societies can be taught appropriate technology suggests that highly intelligent animals should be considered as having some kind of intrinsic moral value.
UPDATE (slightly related): a psychologist finds that human males are much less aggressive if shown pictures of meat. Chimps are somewhat similar - Jane Goodall wrote that the dominance structure breaks down in the aftermath of a successful kill by chimps that were hunting monkeys, and an otherwise-dominant male will beg for meat from a subordinate but won't attempt to take it away.
