As I tell HotkeyNet's users on the program's website, "Cars are legal but drunk driving is not. In the same way, this program is legal according to Blizzard's rules but certain kinds of hotkeys are not. It's up to you to use the program wisely just like it's up to you to drive safely."
Thank you for the excellent comment. It's a shame this topic was derailed - perhaps it can be put back on track.
