I would suggest that the agrument is that Blizzard is using windows, thus they have implicitly agreed to support microsoft products when they decided to use the windows platform. Blizzard cannot claim "our product is windows compatable" and then ban you for using hardware sold by the maker of windows who claims you can use their product with all windows games....
"Windows compatible" only implies that the product should run as advertised under Microsoft Windows (and even then, only on the versions specified... I am pretty certain WoW won't run under Windows 3.11). Blizzard is under no obligation to allow people to use specific hardware or software products to circumvent game mechanics.

Otherwise, stuff like pop-up blockers and anti-spyware would be illegal, since they take direct action against programs and code that are designed to run under the Windows platform.
