Dan Gillmor has an excellent summary of Princeton professor Edward Felten’s encounter with the Digital Millennium Copyright Act. Felten seemingly fell foul of the act by engaging in legitimate scientific research.
Because his findings exposed the security flaws in a music industry anti-copying technology, the industry scurried to gag Felten and his fellow researchers. So far, the industry has been successful.
The issue, as Dan points out, is wider than the Felten case. It really goes to the heart of fundamental liberties of free speech and freedom of scientific enquiry.
