The platform was created by the founding team of Cocos2d-x, the massive open-source game development platform that has spawned hit mobile games including Angry Birds, Clash of Kings, and Badlands.

It's not the team behind Angry Birds, it's the team that created the platform used for creating Angry Birds, it's like saying Epic is the team behind every game that uses the Unreal Engine - it's just not correct.

What's really worring is that the writer of this article either didn't take the time to research what "game development platform" actually means or gave a catchy headline more importance than factual accuracy.
