Microsoft promoting viruses?

As if the already existing windows wasn't vulnerable enough,, Microsoft keeps announcing about the vulnerabilities that it discovers in Windows and releases a patch to be applied for it's protection. If you don't follow verbatim the instructions issued from Godfather M$, hell breaks loose over you. This happened with the recent Zotob virus too. Here's how: In barely 3 days after the announcement of this vulnerability on Windows, proof of concept code demonstrating the exploit was available on the internet, and in two days hence the worms were in their hunting spree. However protective the intentions of Godfather M$ be, for people who did not heed to its warnings in a mere 5 days, they rendered their systems useless.

Or is it a strategy from M$ to stop illegal usage of Windows? The patches are available to legal users only. If it is so, then M$ is trying to cash in at the cost of some legal users too, who happened to be 5 days late in analyzing the situation!
