Zuckerberg is a bad example IMHO, various sources reported on this but Facebook created a space that tolerated and spread incitement to violence that led to thousands of rapes and murders. They saw engagement on hate speech, and promoted the hate speech.
That puts Facebook as the cause and not the people who committed the violence. It provided a technological meeting place, as there are many now, but what did it promote that lead to violence?
