How, then, could runn1ing have submitted this link? Let's look at the page containing the license agreement: http://www.stanford.edu/~laurik/.book2software/ . Let's assume that opening a page doesn't make you agree to any of its content, so you can read the agreement without being bound to it. Look at the source of that page. Beyond the boilerplate "you can't sue us for our software kicking your puppy; we get your firstborn child unless it's ugly", there's a <button> element. Its _onclick_ method? window.location='publishing_this_url_is_probited_by_the_license_you_accepted_getting_here_from_the_previous_page.html'
So simply append that url to the folder in the current page, and you get to the submitted link without ever accepting the terms in the agreement.
Besides, as polemic says, 4(a) says nothing about sharing the download url.
And also, there's no text on the download page that says that downloading any content indicates you accept the agreement, so you can even download the software without agreeing. The license agreement page does say "BY DOWNLOADING, INSTALLING, COPYING, ACCESSING, OR USING THE SOFTWARE, ... YOU AGREE TO THE TERMS OF THIS AGREEMENT."
So, arguably, if you read the agreement page, downloading the software on the download page indicates you agree to the terms. But if you've never seen that page, you haven't agreed to the terms.
Oh, and if it's not obvious, I'm not a lawyer. If you mistake any of this for legal advice, please let me know so I can laugh at you.
