Last Oct, the @RIAA launched a bizarre campaign of legal bullying against #youtubedl, a free/open library that lets people save Youtube (and other) videos for a variety of purposes, including critical analysis, offline viewing, archiving and remixing.
If you'd like an unrolled version of this thread to read or share, here's a link to it on pluralistic.net, my surveillance-free, ad-free, tracker-free blog:
The RIAA attacked youtube-dl under Section 1201 of the Digital Millennium Copyright Act (#DMCA1201) a 1998 law that indiscriminately bans helping people remove DRM, even if no copyright infringement takes place.
