Microsoft did everything it could to destroy openness in the software world. They wrote that the GPL was a virus, hired prominent heads of open source projects like Miguel de Icaza and the name of the Gentoo guy who I forget, and nothing really became of those projects afterwards. And of course there was Netscape and IE up through IE8, IE6 being the most infamous.
Yeah... Microsoft was the bad guy on the block.
(edit: misspelled Gentoo)
It's remarkable that those of us in the Linux world spent so much time trying to unseat Microsoft from the desktop, and what did it in the end was Google and Apple simply working around the Microsoft/Intel (i.e. "Wintel") monopoly.
On the other hand, in the early days IE beat Netscape fair and square in the technical domain, by engineering a vastly better browser, I think it was faster, and it was definitely a lot more stable. And let's not forget how they got AJAX started.
One of the "secrets" of Microsoft's success in those days was their ability to consistently write software that basically worked, something that allowed the dominance of their Office suite when all their competitors but WordPerfect completely failed to get a working Windows version of their software, and WordPerfect didn't crash but had intolerable bugs, like your figures and tables repeatedly moving themselves to the bottom of your document (as reported by a lawyer co-worker and friend who had been a big fan of it on MS-DOS).
