This. I'm really excited about projects like IPFS but I'm not totally comfortable with the "everything persists forever" philosophy as it stands now. Preventing link rot is a very worthwhile cause, but content creators should have control over what persists and for how long (see: "Right to Be Forgotten").
True, it's not exactly the same thing. But I think there is room for a conversation about "published" content as well. The internet covers a much broader scope of content than say print media. I think it is interesting to consider what should be considered "published works" online. Some people think it's fair to say anything you put online is fair game to persist forever. Others like myself think maybe we need a bit more of a fine-grained definition of what constitutes "works" and what persistence properties they should have
