It doesn't matter how legal your tools are if what you're doing is illegal. And this particular tool is pre-populated with copyrighted content. They don't show it in the screen captures (why? </sarcasm>), but all the films in the popular tab are 2013-2014 major U.S. theatrical releases.
Very true, I hope the devs published this somewhat anonymously at least. It's essentially just YIFY torrents taped to the peerflix script with some node-webkit glue.
