Methinks there is a history lesson you haven't learned.

MS didn't get into trouble just for bundling their browser. They got into trouble using every strongarm tactic they could think of to kill the browser market. They broke competitors, deliberately crippled APIs while IE used undocumented faster ones, and put IE in customer faces whether they wanted it there or not. MS used this tactic repeatedly to corner other markets, such as productivity suites. That's why MS got nailed.
