Can WeChat defend its social media predominance by blocking its competitors?

Criticism about WeChat

As WeChat turned eight years old this month, China’s most popular mobile app is facing mounting complaints about its monopolistic behaviour, which has stifled competition in the world’s second largest economy.

The Tencent Holdings-operated super app, which now counts more than one billion active users and is known as Weixin on the mainland, has become such an indispensable online platform that Internet companies introducing competing social media products use it to reach and sign up potential new subscribers.
