Early versions of the individual Microsoft Office products might have lacked some features compared to competitors. Their real innovation was building an integrated suite with consistent user experience. That was tremendously valuable to casual users.

Microsoft certainly did some shitty things in terms of unethical and monopolistic sales practices, but their competitors also made some amazingly stupid strategic errors. In particular WordPerfect was slow to port their product to Windows. And when they finally did, they kept it too similar to the legacy MS-DOS version which was poison for gaining new sales.
