When most people ask, "Who made this" they aren't looking for a character string that matches /[a-zA-Z_0-9]{3,12}/.
They're asking: what person or persons did this, what might I know them for, what do they look like, how popular are they, do they have a logo I might recognize? YouTube and Vimeo provide that information right next to the video, which is where people want it.
If a native app really is preferable, then I'm sure we'll see YouTube wind down their web interface once everybody stops using it. But my guess is that they'll still have an HTML version long after you and I are both in the ground.
