Yeah. I can understand Apple not wanting to open source everything, but open sourcing Terminal.app is scarcely going to give any advantage to competitors (or jailbreakers, or Hackintoshers, or malware authors, or whoever else the folks at Apple who make these kinds of decisions worry about).
I wish Microsoft would open source some more stuff too – although they are much more open source friendly than Apple, especially in recent times. How about open sourcing cmd.exe? Likewise can't see how that could cause any harm. If they did that I'd be eager to send them some PRs (e.g. add a configuration option to suppress the "Terminate batch job (Y/N)?" prompt.)
