WIPO is an unelected organization consisting of people whom the public knows nothing about, yet it is somehow empowered to write laws that the world has to follow. I find that pretty scary, and the history of their treatymaking is pretty scary too. Admittedly, part of my fear comes from the fact that I don't understand how it works and from whence its power comes. I would like to learn but I haven't found a very good source yet.
I don't see any way for individual citizens to influence WIPO, so all we can do is watch on the sidelines and hope they don't get their way. The EFF is doing what it can, of course, but NGOs don't have any real power and typically aren't allowed to speak at WIPO meetings. As EFF said about a meeting last week:
A large and diverse group of public interest organizations, artists, U.S telecommunications companies, consumer electronics companies, and related industry bodies turned up in force to oppose the current draft. Yet again, non-governmental organizations were not given an opportunity to present statements during the meeting. However, EFF distributed an open letter to WIPO signed by over 200 podcasters and podcasting organizations, together representing thousands of podcasters. The letter expressed podcasters' concerns that the treaty would increase complexity for rights clearance and harm the innovation environment for online communication technologies.Anyway, I recommend reading EFF's page on the broadcasting treaty.
