Computer scientist Peter Gutmann made a name for himself when he published his paper “A Cost Analysis of Windows Vista Content Protection” and got worldwide attention for outlining some serious concerns about Windows Vista DRM mechanisms. But Peter Gutmann admittedly doesn’t use Windows Vista and he’s publicly asked for others to confirm his theories and based many of his key assertions on web forum postings as his source.
- Note: As of April 2007 on Gutmann’s website, Gutmann stated: “Can others confirm this? I don’t run Vista yet, but if this is true then it would seem to disconfirm Microsoft’s claims that the content protection doesn’t interfere with playback and is only active when premium content is present”. Peter Gutmann has recently removed this embarrassing admission from his paper hosted on his website after Ed Bott pointed out that Gutmann admitted to never having run Vista and thus couldn’t have done any experiments. An older version of the PDF can be found here which still contains that admission.
