He wasn't complaining that the app isn't working or is useless, he just questions that it needs root and there's nothing wrong if a user doesn't just allow every app SU access.
I mostly prefer open source apps (don't know if the above app is OS) in this case because I can check what its doing and compile it myself or I have the tools and knowledge to see what exactly closed source app do but most users have not and a trust all policy isn't good (even the app is on the Google Market).
I just tested it and it doesn't work (like I thought) without requesting su access.
The part with the setprop command doesn't do anything if it's not executed from root user.
You can check it with:
setprop service.adb.tcp.port 7896
Second command should give back the number you entered above.
The setprop command doesn't return anything if it succeeds or fails, that's why you need to use the getprop to verify the value.
