This is a naive take that belies the reality of pages with a lot of traffic, and is the reason why there can be controversial discussions in the talk pages. I know nothing about the history of this page, which is why I said "if it's intentional" regarding any deliberate scrubbing.

EDIT: On further inspecting the page history, this definitely looks intentional, or at least is a controversial page.
