That article is talking about reproducing things like encyclopedias. The issue there is with the way information is presented, things like formatting and ordering and such. But copyright cannot be used to prevent the spread of information itself. I'm not automatically violating the copyright of an encyclopedia if I learn something from it, then write my own essay on the topic, without explicitly copying the writing itself. In fact that article goes quite at length about this, and includes a paragraph quoted from a judge who specifically mentioned that ideas themselves are not "protected". The general rule is, if it was impossible to convey certain information any other way, copyright cannot apply. Though I must concede one thing: it's quite possible that some countries may have copyright laws which are more draconian. I'm not familiar with the copyright laws of every single country, just my own (the United States).
Anyway, this is all a minor point compared to the point that no one wants ideas. I just happen to be really interested in the topic of the scope of copyright. 
Sorry if I've taken it a bit further than necessary.
