I am surprised that the organizers did not catch this, though I don't know enough to know how much time the organizers had.

For kids, in general, if one kid makes a claim ("I made this," or "This game cartridge is mine") that turns out to be false, there is generally some sort of comeuppance. That could be as simple as the kid losing respect within their peer group, or it could be as serious as parents being informed about the kid commiting a petty crime.

This is important, because it instills society's values (such as they are) in the child. For example, what if kid A steals a game cartridge from kid B, and then kid B retaliates by shooting and killing kid A? That response is generally frowned upon, in most parts of the world.

In my opinion, it would be fine if "the child" was presenting a poster showing the current state of research in microbial recycling of plastics. That's a cool thing for a high school senior or college freshman to do. But to take existing research (stealing), manipulate images (lying), and cast it as their own work (stealing and lying), on a national stage, that requires an appropriate comeuppance.
