>>92285So what. A lot of times through history a term to define a given thing was created way after that given thing started existing or was invented or discovered. America wasn't america until it was cartographied and discovered as a new continent, and given a new name. That doesn't mean what was there before wasn't america (it just wasn't called america until then, just like we didn't call Annoying Orange a vtuber until now).
Also all the time people who doesn't want to be part of a group or definition and/or doesn't recognise himself as part of a group or definition, still is. If a corrupt politician doesn't recognise himself as a corrupt politician, doesn't mean he isn't corrupt just because he thinks so. If he checks the definition for "corrupt politician", he is one, doesn't matter what he things.
Annoying Orange checks the definition for Vtuber. Therefore, he is one, even if he doesn't recognise or calls himself a Vtuber.
