En substance, pour qu'un périphérique marche sous windows vista, le driver doit être validé par Microsoft.
Une des closes de cette validation, c'est la fermeture obligatoire des specs et du code du driver.
Jusqu'à aujourd'hui, certains constructeurs (intel, hp, brother...) ouvraient leur driver ou les specs du matos pour que les devs linux puissent faire marcher le truc sous linux.
Ca ne sera maintenant plus possible, sous peine que le matos soit boycotté sous Vista...
Ca s'appelle un coup d'enculés, car en gros pour qu'un périphérique fonctionne sous Vista, il ne pourra de se fait pas être compatible avec tout autre système libre. Et même les sociétés qui souhaitent que leur matos fonctionne sur autre chose que Windows n'auront plus le choix, sous peine de se voir boycotter et leur marcher réduit à peau de chagrin...
Là c'est encore mieux....
En gros quand tu achèteras un matériel quelconque, tu payeras la protection Microsoft car elle sera dans le firmware du truc.
Une sorte de taxe sur le matériel en gros... Que tu utilises Windows ou non.
Genre t'as un mac, t'achètes une carte graphique, tu files du pognon à Microsoft...
Quand je pense que certaines personnes osent défendre Microsoft dans ses procès pour abus de position dominante...
Le monopole c'est mal!
Elimination of Open-source Hardware Support
In order to prevent the creation of hardware emulators of protected output devices, Vista requires a Hardware Functionality Scan (HFS) that can be used to uniquely fingerprint a hardware device to ensure that it's (probably) genuine. In order to do this, the driver on the host PC performs an operation in the hardware (for example rendering 3D content in a graphics card) that produces a result that's unique to that device type.
In order for this to work, the spec requires that the operational details of the device be kept confidential. Obviously anyone who knows enough about the workings of a device to operate it and to write a third-party driver for it (for example one for an open-source OS, or in general just any non-Windows OS) will also know enough to fake the HFS process. The only way to protect the HFS process therefore is to not release any technical details on the device beyond a minimum required for web site reviews and comparison with other products.
This potential "closing" of the PC's historically open platform is an extremely worrying trend. A quarter of a century ago, IBM made the momentous decision to make their PC an open platform by publishing complete hardware details and allowing anyone to compete on the open market. Many small companies, the traditional garage startup, got their start through this. This openness is what created the PC industry, and the reason why most homes (rather than just a few offices, as had been the case until then) have one or more PCs sitting in a corner somewhere. This seems to be a return to the bad old days of 25 years ago when only privileged insiders were able to participate.

As a user, there is simply no escape. Whether you use Windows Vista, Windows XP, Windows 95, Linux, FreeBSD, OS X, Solaris (on x86), or almost any other OS, Windows content protection will make your hardware more expensive, less reliable, more difficult to program for, more difficult to support, more vulnerable to hostile code, and with more compatibility problems. Because Windows dominates the market and device vendors are unlikely to design and manufacture two different versions of their products, non-Windows users will be paying for Windows Vista content-protection measures in products even if they never run Windows on them.
Here's an offer to Microsoft: If we, the consumers, promise to never, ever, ever buy a single HD-DVD or Blu-Ray disc containing any precious premium content [Note O], will you in exchange withhold this poison from the computer industry? Please?
