I get the point, but I think in these cases it is because when you have someone famous, one usually has no idea who their spouse is (unless they are famous too). Steve Jobs is going to get more key words hits and click throughs because people know who he was. I’ve never heard of Laurene Powell before, and unless I was a fan of the Atlantic, why click through?
Like if I dated Scarlett Johanssen and somehow made the news, they would probably lead with something like “Scarlett Johanssens boyfriend has a Boba Fett collecting problem.” because no one knows or cares about who Mister.44 is.
Now if Beyonce was described as Jay-Zs wife or Angelina Jolie as Brad Pitts ex, vs their actual name, that would be more messed up.
Note too, when anyone non famous does something too, it is nearly always “a man” or “a woman” or even more likely “a Florida man”.
