For all intents and purposes all creation is incremental. In the sense that someone sees something, and says "Hey, that's a great idea, but it would be better if I changed it like this...".

Prove this to yourself: find out who invented television.

So, weaker copyrights would encourage incremental innovation, the kind that really takes place. Adding a "fair use" doctrine, which is "radical" reform in the article, almost certainly only helps the content creators in that it frees up other people to reference previous creations, driving interest in, and use of, those previous creations.

As far as radicalizing copyright into so-called "Digital Rights Management", remember: "DRM is about political and economic subjugation".
