Fascinating: The Court of Appeals ruled that for a software licensee's violation of a contract to constitute copyright infringement, there must be a nexus between the license condition and the licensor’s exclusive rights of copyright. However ... that a finding of circumvention under the Digital Millennium Copyright Act does not require a nexus between circumvention and actual copyright infringement.

The DMCA's anti-circumvention section appears to be the only thing that preserved parts of the original finding. Perhaps the next time this law is up for review, some less onerous terms can be placed for reverse engineering for the purpose of interoperability.
