It seems like they made the same mistake as youtube-dl back in the day. If you develop a tool that can be used for piracy, do not straight up advertise that in your readme/documentation.

If you create a YouTube downloader, do not show it downloading music from major labels, use for a creative commons track for the demo instead.

And dont say in the short description of your repo that this tool is meant to steal books from an online lending library.

Yes, it does. You can also use the tool to check if a file is cached (just run it without any arguments for that).
