As others have said, that this used to be Ellen Paige is the story here, so there's no way to talk about it and not mention that. It's not like this is some random reference to a high profile trans person and the old name is being dropped in for no reason.
I mean it's the same person, who always was Elliot Page.
No he wasn't. Paige might have always felt like a man on the inside (not sure if he commented on that) but the name change only happened yesterday. Muhammad Ali wasn't "always" Muhammad Ali.
