I really don't see this update as being in any way an attack on affiliate websites.
fred9989's post refers.
On key search term yesterday, only two of the top ten (the first at #7, the second at #10) had any outward links at all, and those had only a couple each.
This morning, #1 position has been taken by a 7-page site with scarcely enough content to put a link in, so outward links cannot be the only issue.
