A few days ago I inadvertently caused a bit of a fuss. In writing about GOG's Time Machine sale, I expressed my two minds about the joy of older games being rescued from obscurity, and my desire that they be in the public domain. This led to some really superb discussion about the subject in the comments below, and indeed to a major developer on Twitter to call for me to be fired.
Fascinating article on Rock Paper Shotgun from John Walker on why he thinks software copyright (and possibly other kinds too) should come with a much shorter shelf life. Although ostensibly about videogames, much of it could be said to apply to recent events in mobile OS development too.
