QQ users have severely decreased, with at least 10 million users lost.

Data shows that the user churn situation of TX is extremely serious. Who made QQ lose the most users? Where did the lost QQ users go? What chat software do they use instead of QQ?

First, 360

The reason why QQ lost the most users was still due to the choice between 360 and TX at that time. I believe quite a few friends chose to uninstall QQ.
