Paul Bryant has a blog post entitled How Microsoft could crush Google in one easy step. Seriously. where he writes

Henry Blodget has a post up on "One way for Microsoft to Kill Google" It's interesting, but I think there's a much easier and faster method that Microsoft could use to more effectively “kill” Google tomorrow if they so chose.

It’s more than a little bit evil - - but on the other hand, I never heard Microsoft promise that they wouldn’t be:

So what is it?

The height of simplicity. Introduce an integrated ad-blocker to Windows (purely as a customer service, of course) that blocks all Google ads in both IE and Firefox.

Allow users to temporarily or permanently turn off the blocker if they choose. (Knowing full well that 95% of users use just the default settings.)

MSFT would probably need to block their own ads too, in order to make the effort legitimate, but how big a loss would that be for them really, on a relative basis?

For G, on the other hand, it would literally eliminate their entire revenue stream. Overnight. And Microsoft could push this out via a Windows Update in a few weeks time, at most. Buy the very excellent AdMuncher and bundle it if it’s too time consuming to build.

Part of me hesitates to point this out (in fact, I first thought of it a couple of years ago, and didn’t say anything for that very reason) but I can’t possibly be the only person who has thought of this, right? What am I missing?

Usually when I see a post like this, I just post a comment pointing all the ways the idea is stupid problematic. However given that the Paul Bryant's blog doesn't allow comments and I'm supposed to be on vacation, I'll just let the merits of this idea stand on their own without further comment.
