Not his fault and pretty cool he was in touch with users of the library enough to catch it and stop it.
Always figured I'd do Cocos2d-x or Unity for any serious game I do next. I used Cocos2d before and written Unity plugins before. I even have a contractor working on a Unity project right now. Will have to give libgdx a few extra points when deciding in the future, though, for having a caring maintainer.
I actually wrote an OpenGL game engine for Android back before any of the later things came out like Replica Island, AndEngine, the Cocos2D port, etc.. Almost makes me wish I'd open sourced it. It did have some awesome stuff like batching all the sprites with similar draw states together into one draw call.
