Thank you very much, Ms. Quach.
I understand Professor Boyer's position but I take a different view. I don't think that exceptions and limitations like fair use are expropriations of proprietary rights. The default situation is not that a copyright owner has the right to control every use of its work and every time you limit that it's an expropriation. The default is the opposite.
The default position is freedom of expression and the liberty to do whatever you want. We provide copyright protection as an incentive to encourage investments in creativity. To quote a phrase that the Supreme Court of Canada has used from my former graduate supervisor, Professor David Vaver, “user rights are not just loopholes”. I think that's important. It's a different view of the issue.
