I may be wrong on this, but the judge ruled that Microsoft was a monopoly. As much as we'd like it to be, that's not illegal- case law has shown that companies are perfectly within their rights to attain a monopoly as long as they do it competitivaly, which M$ will now be trying VERY hard to prove that they did. This judge was authorized to rule on findings of fact, which was basically limited to whether or not M$ was a monopoly or not, NOT whether it was an illegal monopoly or not. That gets decided later, and a different question of law. So even if this ruling implies that Microsoft was "naughty" the judge isn't yet empowered to legally rule on that (he can say so all he wants, but that's not the ruling, just like Supreme Court justices go on and on about things that may not bear on their actual findings).
