Microsoft Confirms DRM Driver Crippling in VISTA

I got some feedback from some DRM doubters at the beginning of the year when I talked about The Perils of Windows Vista and Built-in DRM. I wish that I was wrong, but no such luck. From the horses mouth comes confirmation of every horrible charge leveled at Vista by Gutmann

Windows Vista Content Protection – Twenty Questions (and Answers)

Over the holidays, a paper was distributed that raised questions about the content protection features in Windows Vista. The paper draws sharp conclusions about the implications of those features for our customers. As one of the Lead Program Managers for the technologies in question, I would like to share our views on these questions.

(here are some examples of the Microsoft version of Q & A…ed)
Will echo cancellation work less well for premium content? (LESS WELL??? WTF??? ed)

We believe that Windows Vista provides applications with access to sufficient information to successfully build high quality echo cancellation functionality.

Will Windows Vista content protection features increase CPU resource consumption?

Yes. However, the use of additional CPU cycles is inevitable, as the PC provides consumers with additional functionality. Windows Vista’s content protection features were developed to carefully balance the need to provide robust protection from commercial content while still enabling great new experiences such as HD-DVD or Blu-Ray playback.

What is revocation and where is it used?

Renewal and revocation mechanisms are an important part of providing robust protection for commercial audiovisual content. In the rare event that a revocation is required, Microsoft will work with the affected IHV to ensure that a new driver is made available, ideally in advance of the actual revocation. Revocation only impacts a graphics driver’s ability to receive certain commercial audiovisual content; otherwise, the revoked driver will continue to function normally.

Be sure to read the whole thing… especially the comment section.

UPDATE: Gutmann responds to the MS “Blog” entry directly and tries to unravel the PR spin. The technical comments have been integrated into the main body of the writeup.
