When Facebook acquired Whatsapp for $9 billion in February 2014, it bought an app that prides itself on being a no-nonsense, straight-forward messaging service. WeChat is the antithesis of this. It’s a messaging service, a social media platform, a marketplace and even a way to browse the internet. It’s the app that does everything. While companies and app developers in the US and Europe race to unbundle their services into efficient single-purpose apps, WeChat's parent company Tencent continues to add feature after feature.
