If they really want change, it's time for them to dispassionately consider their situation. The way to "beat" piracy is to consider it as a competitor, which it is. When I was a kid, everyone downloaded raw mp3s and now that number is a fraction of a fraction because there's 1) YouTube and 2) Spotify et al. You can listen to music all day with ads and not pay a cent, or you can pay a reasonable fee and get all the HQ music you can eat without ads. Publishers continue to screw content makers, but that's another conversation.
Just trying to ban pirate sources is a wonderful dream for publishers for sure, but there's no way it can work. Scientific papers are just too easy to share, the need for them high, and the current pricing too insane for it to be otherwise.
