But if I remember from back in the day, the DMCA doesn’t have any exception for that. This is why CD ripping was legal, while DVD ripping was not. It had nothing to do with fair use or backups, but rather that DVDs have encryption, and CDs do not. Circumventing that encryption for any reason was illegal.

I don’t think it has changed, but it’s been a hot minute since the Cypherpunks all wore DeCSS T-Shirts…
