After reading this weeks material it has become clear to me that there is two sides to these different licenses. One might even say that it is a necesary evil
On the one hand I can see the value of the creative commons licences in freeing up the material for people right accross the globe to use and re-use. It also places some restrictions on how, where and when one might use the material. This is were the two sides I mentioned earlier comes in.
On the one hand it protects the author or creator of the material to some extent, for example fair use of material. On the other hand it might place undue and confusing restrictions on the work (I know I was initially very confused)and some individuals might think it easier just to copyright the work and be done with it.
In my opinion these licenses are a good thing, if they are used in the right instances and do not work against the ideal they are trying to uphold
