Seriously, wine helps Microsoft more than it hurts them. It provides a measure of compatibility but doesn't allow developers to write first-class applications for Linux. In other words, it maintains the platform lock-in. What's not to like about that?
Anyone, your absolute statements have no meaning. There is no way to quantitatively measure how much Wine helps Microsoft or Linux. Dismissing the notion that running certainly Windows applications on Linux is at the very least desirable for some in the short-term is ridiculous.
