That seems an entirely different issue.

If you are using a program to which you expect connections to be made,
and it includes malware, this is a problem whether you have a nice clean
GUI interface, or are forced to edit iptables by hand. Such a thing will
bite even very technical, security-minded people, and there is no
/completely/ secure solution to it (even compiling from source has been
demonstrated to have problems for this). This is what digital signatures
are intended for.

Now, if someone enables connections to an application that's not
supposed to be communicating over the Net... I don't really see how we
can protect someone too well against that, without stepping over some
lines that I don't believe we have the right to cross ("we know what's
best for you better than you do...").
