Read it and weep, folks. In the Order, every single geek argument is
slammed, and slammed *hard*. In particular:

“This Court finds, as did both the Corley and Elcom courts, that legal
downstream use of the copyrighted material by customers is not a defense

San Francisco – Consumers suffered a setback to their digital rights
today when a California federal court sided with the major motion
picture studios in ruling that a company creating tools people can use
to make backup copies of their DVDs is liable under copyright
law. Citing the Digital Millennium Copyright Act (DMCA), the court
ordered 321 Studios, creator of DVD backup tools, to stop selling its
DVD Copy Plus and DVD-X COPY products within seven days. 321 Studios
is likely to appeal the ruling.
