Slate has a really interesting article, Freebooting: Stolen YouTube Videos Go Viral on Facebook, that dives into a new phenomenon where YouTube videos are stolen and then uploaded to Facebook.
As one YouTube creator described it:
"In May, he posted a YouTube video on how to make gummy candies in the shape of Legos, and it garnered about 600,000 views in the first 24 hours.
Meanwhile, on Facebook, someone else’s ripped version of his video was approaching 10 million views. “The worst thing is just the shock of how viral they go on Facebook compared to the ones I post on YouTube.”
