just regular sites, articles and blogs linking in the regular way they always have

Natural linking destroyed by a short-sighted, lazy solution. Nofollow does not stop spam and fluff, bots and idiots post regardless. As your post illustrates perfectly, it increasingly means that providing content that gets cited freely is of little consequence now. You HAVE to engage in marketing.
