But inspired by the DMCA, the EU has also adopted anti-circumvention legislation. Though I'm dubious either would apply here, as this would be very difficult to spin as a copyright issue.
Actual text of the directive: http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:320... (see Chapter III, containing things like "Member States shall provide adequate legal protection against the circumvention of any effective technological measures" and then going on to define "effective" to mean "not necessarily effective")
Some parts have been amended (for example, copyright duration has been expanded from 50 to 70 years after death), but I believe the anti-circumvention parts to be unchanged. I'm not sure how to find up-to-date codified versions of EU laws, though.
