The SDMI group had issued a chalenge to try and break any of their secure music algorithms. This chalenge was covered under an NDA that was agreed to via a click through web page. A university profesor heard about the chalenge and with the help of some other profesors proceded to break all the algoritms. They did not click through the SDMI groups NDA web page, this was completely independant. They were going to present a paper on this but the SDMI group stopped them by threatening to sue.
So SDMI has been broken and it looks like the SDMI group, or at least some of them, are against free speech.
