It's funny, because the anti-trust lawsuit revolved entirely around the browser wars and "bundling". However, that law is rather vague bordering on poorly written (many instances of "bundling" are often a benefit to the customer) and was likely misinterpreted besides. Moreover, Microsoft won the browser war as much on releasing an outright better browser in a key time frame when Netscape was having extreme development trouble. Even without the bundling Netscape was at a huge disadvantage.

More so, the truly anti-competitive behavior of Microsoft (where they effectively bribed OEMs to prevent them using other OSes) didn't receive nearly as much attention.
