You are a brainless fanboy.
This isn't a minor issue, it's a huge mistake. It's the kind of thing Microsoft did for years when security wasn't part of their culture. I simply can't imagine you reacting that way to software from any other source.
Or, differently: do you really think that people who can run commands in your Terminal window can't already take control of the OS X kernel?
Also: I object to being designated HN's "resident security expert", and I didn't put my comment at the top of this thread.
