Holland also co-founded the CCC's hacker magazine Datenschleuder in 1984, which praised the possibilities of global information networks and powerful computers, and included detailed wiring diagrams for building modems cheaply.

"Connecting a do-it-yourself modem was punished more severely than negligent triggering of a nuclear explosion", Wau Holland famously said about this situation.

He compared the censorship demands by some governments to those of the Christian church in the Middle Ages and regarded copy protection as a product defect.

In his last years, he spent a lot of his time at a youth centre teaching children both the ethics and the technology of hacking.

Holland died in Bielefeld on 29 July 2001 of complications caused by a brain stem stroke from which he suffered in May.
