Yes, it's been a significant source of frustration. In fact, I had a personal experience with my daughter, who created a video after she participated in a program called March of the Living, where she went to concentration camps in Europe and then on to Israel. As part of the Ottawa community, she interviewed all the various participants who were alongside her, created a video that was going to be displayed here to 500 people. There was some background music along with the interviews. They posted it to YouTube, and on the day this was to be shown the sound was entirely muted because the content ID system had identified this particular soundtrack.
They were able to fix that, but if that isn't a classic example of what non-commercial, user-generated content is supposed to protect, I'm not sure what is. The fact that Google hasn't tried to ensure that the UGC provision that Professor Gendreau mentioned, which, as this example illustrates, has tremendous freedom of expression potential for lots of Canadians, is for me not just disappointing but a real problem.
