A lot of people do not have a perspective on how greedy Microsoft was.
Bill Gates is one of the richest people in the world today, not by gathering in circles and singing happy songs. The guy was a monopolist.
They wanted everyone to use Microsoft Windows, code in Visual Studio, do their office work in Office, browse the web in Internet Explorer, have a Microsoft e-mail, chat using Microsoft services, and you get the idea.
And a lot of that was possible by having Windows preinstalled in new computers, and bundling software with Windows, like Internet Explorer. You could argue Apple is similar, but I do not think Apple is interested in a monopoly of the size of that planned by Microsoft.
