The problem with moral is that it's in the eye of the beholder. While legal is described very clearly on paper.

And how is it moral to be nice with immoral people ?

Now I do believe it's good to let a chance to do the right thing. But if not, it must be followed by actions.

E.G: I would add to the licence that it is illegal to give technical support or to provide a commercial service related to the product with a violated licence, for all the product with the same licence. If you can't get support for any of your linux servers, or you can't even rent a new VPS, you'll think twice about compliance.
