I'm sure they, like most publications, have a house style guide that dictates things like this to ensure consistency across articles and over time. They'll presumably follow that style guide as it now stands until it's updated, at which time they'll change all articles to conform to the new style. Depending on the circumstance, what a person or entity wants to be called isn't the only consideration when deciding how to refer to them in print, and publications don't generally tend to want to leave it up to the whims of individual authors.
