Fair question -- here are a few examples:
On Wikipedia's entry for Facebook, there's no discussion in the 2006-12 section about Facebook's steps to monetize the site around targeted ads. That has had gigantic global impact and was the impetus for Meta/Facebook's emergence as one of the world's most profitable companies. But Facebook never "announced" that it was doing this. So the entry is clogged with a string of quite minor "announcements" that it did make -- touching on short-lived headquarters moves, feature tweaks, obscure awards, etc. instead.
Wikipedia's entry on Maine Republican Senator Susan Collins is an achingly long list of votes she's taken over the years, or one-line quotes about her positions at various moments in time, without any effort to write coherently about what's been consistent or evolving in her political views. Also absent is any nuanced sense of how Collins's journey interacted with changing political tides. We end up with a 20,000-word string of factoids that goes on forever, with scant insight about her enduring impact, core principles, etc.
