GMail on GetJar

They say seeing is believing, but I'm still not sure what to make of this one.  Google's closed applications -- the ones they keep a tight rein on and not allow just anybody to use -- apparently are available through the third-party market GetJar.  Not just Gmail that you see pictured above, but Google TV remote, Maps, Search, Books -- they're all there.  We're assuming that this is legitimate and not a mistake (GetJar is a reputable site), but we're baffled at how this came to be -- especially since Google's apps also need additions to the Android system framework to actually run.  I can tell you that they work (I tested with Google Music and YouTube -- can't afford to wipe out my Gmail app just yet), but I can't tell you why.  Hit the link and give it a try yourself.
