Ripping a DVD is and was not a federal crime. The DMCA had carve outs for personal use and DeCSS was free speech (as argued and won by the EFF).

Using DeCSS to rip your own dvd was never illegal.

I'm not seeing personal use as one of the DCMA exemptions to prohibition against copyright protection circumvention: https://www.ecfr.gov/current/title-37/chapter-II/subchapter-...

The exemptions seem to be for pretty specific cases. Have you got a link to the EFF case?
