I know it's marketing, but it seems like a great way to introduce people who aren't aware of (or care to learn about) their YouTube content, to their real name by showing both.

People choose screen names and stage names for many different reasons. Some like Michael B Jordan because Michael Jordan was already the more famous Michael Jordan. However more often than not, they do it for the practice of anonymity or branding. Which are intentionally separate. So it's kind of self defeating to merge the two.

I've watched Markiplier since roughly the mid 2010s. I never cared and he never really broadcast any part of his private life until recently. The reason I know his last name, is only because several outlets felt the need to dig it up and publish it regarding the movie. In years past when he had his mom on for a few streams, she was momiplier. He's always referred to his girlfriend now wife as just Amy. And as far as I'm concerned she can just be Amiplier. We torture celebrity enough.
