Microsoft has started building DRM into most of its content tools - MS Player and MS Reader, for instance. Microsoft has devoted a large number of resources into DRM research, and owns large stakes in companies that hold patents in the DRM arena (such as ContentGuard).
Now imagen that Microsoft incorporates DRM into its office suite - MS Word, Powerpoint, Excel, etc. On the surface, this seems fine - the creator of a document can then have more control over the use of that document when it gets distributed. Except for the fact that by allowing any user to restrict document use in very narrow ways, fair use gets trodden upon. The amazing thing is that it won't be Microsoft who gets blamed; it will be the creator of the document who sets the access restrictions. MS Word will just be the vehicle of information slaughter.
The problem here is that Microsoft is providing users with a technology that, as its primary function, infringes on fair use. Of course, it won't be viewed that way - if it was, it would be token to the same constraints under the DMCA as software produced by ElmSoft. Microsoft is opening the door to a world where information restriction is the norm, and information access is a strict economic commodity (note: information access as the commodity, not information itself).
As if all of this isn't scary enough, look at Microsoft's plans for IE. They still see IE as the operating system front-end. They see it this way in part because it helps them have control over the entire information stream, from creation to viewable product. My guess is that seperate tools like Microsoft Reader and MS Player will be disappearing in the coming few years; Microsoft has put little into developing new features for MS Reader. Instead, all information access will be through the browser, Microsoft's browser, which will contain DRM technology built in. Now, you can go to a website, but you can't view the source code, and you can't print what appears on your screen, unless explicitly allowed by the website creator. You can't link to a website, unless explicitly allowed. Heck, you may not even be able to see the URL for the website, unless explicitly allowed. And in Microsoft's world, all information - HTML, video, sound, etc. gets viewed and used view the browser (and perhaps along with their office products).
So, is all this a certainty? Certainly not. Hopefully it is not a probibility. But it is a possibility - and we need to be aware of these types of possibilities. There is big business in information access, and those who control the access, in reality, control the information.
