On AWS, S3 has a downloader-pay option since basically forever. Maybe a non-technical user would be baffled by this, but a HN user won’t have trouble paying for the download using their existing AWS account. This would be a fine solution if the cost of distribution is the only concern, without considering royalty for copyright.

Most places (all??) aren't going to be doing AWS->AWS transfers like that. They'll have a web portal with you can use a payment option that ultimately generates an expiring authorized URL.
