From our Manual of Style:

"The histories of characters and events are generally supposed to be written as if you were an omniscient historian living in the DC Universe, not just some random guy. Try to write everything from an in-universe perspective and describe things as in-universe as you're capable of doing. This is not required where you directly need to talk about publication information."

That being the opposite of an out-of-universe perspective, which would talk as though the DC Universe is fictional, and owned by a company called DC, whom you should never mention in a history section - which is what Tupka is talking about.
