There was a reason it was browsers.
At the time there was rather a lot of software written against the Win32 API and nothing else. It was a moat. You needed that software, so you needed Windows. The web threatened to bridge the moat -- if people write web applications for Netscape, and Netscape runs on not only Windows but Mac and Solaris and everything else, no more moat.
So the strategy with Internet Explorer was to make it the dominant browser on Windows (which was 90% of desktops), and then add all kinds of IE-specific features and get web developers to use them, so their web pages only worked in IE. Then the user gets a dependency on a web page with an Active X control that runs on Wintel but not Mac/PowerPC or Solaris/SPARC, so they have to use Windows. And they have to use IE, which enables more web developers to target IE instead of open standards.
The problem wasn't that it was free. The problem was that it was free and non-standard and the non-standard bits were tied to Windows.
