The article is interesting, maybe the EU has a valid point.

From Yahoo's article:
"EU antitrust regulators fined Microsoft a record 497 million euros ($665 million) when they ruled a year ago that Microsoft abusively wielded its Windows software monopoly to lock competitors out of the market.

They ordered, among other things, that Microsoft share Windows server code with rivals so their products can better communicate on networks with machines that run Windows operating systems.

Microsoft decided it would provide the information through licenses, which Todd said the European Commission (news - web sites) felt were too expensive."
