> They don't want it to look stale. But that can also be extremely counterproductive when the content you publish has a natural expiry date - and in many areas of expertise (pretty much anything other than pure marketing talk) things change over time.

If you have a date on the page it's far less likely to happen. COVID recommendations and measures are one such (rather extreme) example where many big players endangered their credibility because they've failed to properly mark the outdated content.
