It's CC-BY. It would be the same as Britannica using text from Wikipedia (legitimate and legal, but possibly innappropriate).

CC-BY is the license Wikinews is under; Wikinews didn't have contributors uploading videos at the time. Actually, Brittanica does use images from Wikipedia & Wikimedia Commons, so not sure that's a good example.

Wouldn't it be the same as news agencies using photos from Reuters? Except here, using the CC-BY license rather than money.

I was looking through the other media Al Jazeera has released, and it appears that the English Wikinews didn't end up using any, even where no other free media existed, quite unlike other projects.

This looks like it's part of a bizarre attitude to how to be a news website, very different from that of Wikipedia to being an encyclopedia or any other Wikimedia project to its aim; this is one of the reasons I don't contribute to Wikinews.
