It shows a recency bias, which is probably unavoidable. I'd hope that, as time passes, there are mechanisms to archive (not delete!) pages that seem unimportant. However, while this level of coverage may present a noise problem for average users, it will be a gift to future historians. How much material about the historical figures you mention was simply lost?

That being said, there should be absolutely no regard for "sensitivity" or the fact that Musk is a living person. He is a public figure wielding a ridiculous amount of resources to reshape the world as he sees fit. Regardless of his virtues or shortcomings, his power makes him somebody that should be watched closely. He helped shape the last U.S. election, played a key role in this presidency, and promises to continue his influence in the mid-terms. It matters if he's a Nazi.

Kudos to Wikipedia for leaving that page up.
