I'm aware, I just don't see how this would provide an advantage over already existing methods like hitboxes, or regular keyboards.

Your original comment read "keyboard provide a substantial advantage" without specifying an advantage over what, so I assumed you meant an advantage of the most commonly use controllers, not advantage over other stickless controllers. Even ignoring that, stickless controllers are still very much a minority, so an advantage over traditional controllers would still be a large advantage over the pool of competitors especially at lower levels.

If it provides no more advantage than an existing non-standard controller, than this news piece is a complete non-story. Or at least, that bit of the piece is a non-story.
