That seems to be the norm in journalism these days. Link to ads instead of sources. Thanks for the link.

I wonder who shot the footage. It seems like they asked for something, in a playful way. Both the men and women seem amused, or even flirtatious. The woman at 1:27 is clearly flirting, and the women at 3:56 and 4:06 stick their tongues out. And a few of the men are winking.

Isn’t it linked in the article on the word “footage”? That’s what I see at least...

Oops, missed it because of the lighting I guess. Still, why put the mini-documentary inline and not the original? It was also linked from the mini-doc, but that's indirect.

Yes, same video.
