No one has demonstrated that simply removing content that's "old" means we think a site is "fresh" and therefore should do better. There are people who perhaps updated older content reasonably to keep it up-to-date and find that making it more helpful that way can, in turn, do better in search. That's reasonable. And perhaps that's gotten confused with "remove old, rank better" which is a different thing. Hopefully, people may better understand the difference from some of this discussion.
