Or maybe MS thought that browsers were so useful that users would want a browser with their OS? You can bundle a product without tying it. Contrast the following scenarios for me, please:
- distributing a copy of Internet Explorer for free, or free download, with each copy of Windows sold
- integrating Internet Explorer into the very guts of Windows so that it would be very difficult if not impossible to remove, and present onerous licensing terms to OEMs that prevent them from shipping any other browser on Windows systems
Guess which one's legal? Guess which one MS did?
