I seem to recall that it wasn't bundling the browser so much as dictating what the computer distributors could do. Microsoft did a Darth Vader vs. Lando Calrissian ("But we had a deal!" "I have altered the deal. Pray I do not alter it further.") with the license distribution arrangements they had with vendors like Dell. The vendors were allowed to install a bunch of crapware in their standard Windows distributions that come on the hard drives of new PCs, but they were forbidden to pre-install Netscape, thus cutting off Netscape's air supply. MS threatened to unilaterally change the terms of the license distribution if the vendor installed Netscape. This was an abuse of Microsoft's monopoly power, as the PC vendors had no choice but to do what MS said, since there was no way for the vendors to compete with other PC makers if they couldn't pre-install Windows.
This is possibly covered in the article, but I haven't got around to reading it yet.
