I think it really depends on the terms and conditions of the promotion. If it states a date, and you acquire the book past that date, it’s not acquired under the terms and conditions of the giveaway.
That being said, it’s really stupid of the site not to take the files down. The Wayback Machine cannot be faulted for storing sites that contain links that should not work anymore.
If however, the download comes from the WM servers, it is up to them to delete those files.
In any case: if the promotion is over, you are not entitled to that free download anymore.
