No, he should sue the sites which host the original article IF they're causing a harm. Since the articles are factually correct and dated appropriately, I don't think any harm is being done to him merely by the presence of those articles.

What do you think should happen when someone searches "Tom Cruise"?
Should it somehow show you all 14,724 people who happen to have that name, somehow cleverly giving equal visual weight to all of them? Not accidentally listing one of them first, etc?
No, it's not harmful discrimination. This is a flawed line of thinking.
