There's a difference between immoral and illegal. Just because we
don't want to forbid it, doesn't mean we have to like it. The license
takes the stance "we don't know better than you what your needs are",
but it doesn't mean we can't judge your behavior later.
As a similar situation, freedom of speech isn't freedom from consequences,
it's just a freedom from punishment. If you say stupid things, you will
get bad reputation and you will get criticized. In our case, if you do
bad things with our code, we will make moral judgements about it, we will
criticize you, we just won't take you to court.
Just because you can build baby mulching machines doesn't mean we have
to use them or like them.
