>Of course it is not smart to ignore the text of the license. The preamble makes clear what the intent is of the legal clauses. In case their is any doubt how to interpret a particular clause one looks at the intent to see that "any patent license obtained for a version of the library must be consistent with the full freedom of use".
Sure? OK, let's try:
The book club is a non-profit, for-good, honest, no-nonsense organization that strives to bring its members peace, prosperity, happiness and easy access to their favorite books with absolutely no hooks attached
666. (f) If you have read this far, we will now inform you that we will send you a few books per week at not exactly premium conditions. They will be a random choice of the old stuff we could not sell otherwise. You may not give them back and pay within three days.
Construct a slightly less contrived example if you wish, but still the fact remains: the preamble is not legally binding.
