I can't help to agree with big_D here. I agree not because the information is available wrongfully (which it isn't), but because without meticulous inspection, Google is presenting this information as their own contribution of content. If people like the presentation of what Google shows them, then they will surely know the name Google. But what they might not know is that the work of others has made Google's presentation possible, and they might never know the names of who did the work, only Google's.
Dunno. In the end, I guess it is how many people still disallow Google to do something, rather than allow. Of course, is Google seriously considering others considerations when you read...
"...Google had spent tens of millions of dollars on its ContentID tech,"
A whole "tens of millions"? They intentionally loose more than that per day for artists for their own advertising.
