Kaggle discriminates prizes based on where you are born

tl;dr The United States Department of Homeland Security sponsored a Kaggle competition, and the prizes cannot be given to non-US citizens. This is due to US laws preventing security organizations from paying foreign contractors.
Nothing particularly new or surprising here, and it makes sense that a government security organization wouldn't employ foreign citizens.
Not only the nationality issue, but this competition also prevents competitors from opening publicity, including future research and writing blog posts about it. Seriously why they are willing to host this thing in a public community?
This competition significantly degrades the true value of Kaggle and DHS should host the competition themselves not using this kind of platform.
