yt-dlp has a strict policy against cracking DRM
This is how it stays legal in the USA. Bypassing DRM is a DMCA violation (section 1201), but just downloading freely-available content is totally legal.
Its predecessor, youtube-dl, was subject to DMCA takedowns from the RIAA, and they had to get the EFF to help. yt-dlp doesn't want to experience the same issues.
