Did they copy Hangouts or Google copied them?

I believe this is a very old app. It used to be open-source and free. Don't know the current status.
It's basically an example/Demo app for how the XMPP and Jabber are used for chat services- text, audio, and video.

It's free currently. And updated recently. But looks a lot like Hangouts.
