> Sony claimed the Protected Work was *theirs*
That's the problem: Sony didn't claim anything. It was just some pattern matcher whithin the bowels of Google. Oops.
On the Sintel video from the BlenderFoundation account on YouTube:
This video contains content from Sony Pictures Movies & Shows, who has blocked it on copyright grounds.
That is an explicit claim associated with Sony Pictures Movies & Shows. To get that, Sony had to upload content to the YouTube content system saying "I own this content. Anyone matching it is in copyright violation."
Also, the content ID system does not support Creative Commons or similar license usage (can use with attribution, can/cannot monetize the content, etc.) and does not work with collaboration/team events on multiplayer games, podcasts or discussions.
Actually, the Norman invasion resulted in Middle English (Chaucer) which incorporated several French words into Old English (e.g. Beowulf, which originated from the Anglo-Saxons migrating from Germany), accompanied with a shift in pronunciation. At the start of the Tudor period, this evolved into Early Modern English and had a more radical shift in the way the vowels were pronounced. This then evolved through Shakespeare and spread throughout the world into the English we know today. Even through Old, Middle, Early Modern and Modern English, pronunciation and dialectal phrases varied from region to region like they do today.
Trying to be happy is like trying to build a machine for which the only specification is that it should run noiselessly.
