But the meaning would change completely. "Ur" is used here in the German sense, meaning "original" or "source". It also refers to the ancient Sumerian city, Ur. So the headline actually means "FB’s Plan To Automatically Share Original Ancient Sumerian Data With Sites You Never Signed Up For".
Thanks for explaining that. I misread it at first-- I thought it said FB's Plan To Automatically Share Nur Data..." where Nur is short for Nur Illahi, the divine ray of enlightenment, i.e. they were planning on sharing data on optical drives.
What a terrible misunderstanding that would have been. Cheers to you, good sir.
