I'll make three comments here.
One, on the response to go to the markets and negotiate access, you forget that copyright is about exclusivity, right? Copyright gives control and the power to say no.
Copyright has a dangerous potential for being a tool of censorship, especially when you're talking about documentary filmmakers or other news organizations, or other critical organizations that want to embrace their section 2(b) charter rights--freedom of expression--and participate in a robust way in debate about an entity, about anything, right? You've got some problems.
The second point I'll raise on the constitutionality is that I think there are two constitutional problems. One is Professor de Beer's argument that any circumvention rules are about devices. It's about property. It's about contracts at the end of the day. It's not about copyright. It's not about intellectual property. So how do you get under the appropriate federal head of power? It sounds a lot more like property and civil rights, which is a provincial sphere of authority.
Then the second argument is a charter argument, right? We don't recognize this often enough. Section 2(b) guarantees freedom of expression. Copyright attaches only to expression. The overlap is 100%, so if you don't get the balance right in federal legislation, in the Copyright Act, you have a section 2(b) problem.
If you look at what anti-circumvention rights are doing, what anti-circumvention laws are doing, and the very narrow scope for avoiding liability for circumventing and the very real probability that you won't get permission to circumvent from a rights holder in all cases, particularly in critical cases, you have a section 2(b) problem as well.
