Tencent, WeChat and Chinese censorship: Does Naspers have a free speech problem?

Naspers appears to be a company comfortable with contradiction. On the one hand, it owns Media24, the largest independent media group in South Africa and a vocal critic of any attempts to restrict media freedoms in South Africa. On the other hand, most of Naspers' revenue, and its entire market cap, comes from its large stake in Tencent, the Chinese social media giant that is deeply complicit in official Chinese censorship efforts. Can the two positions be reconciled? Or is this an unsustainable hypocrisy that will not end well for South Africa? By SIMON ALLISON.
