MS Office is actually a counter example of this. It was much worse than Lotus 1-2-3, Lotus Notes, and WordPerfect. They crushed the competition because of vampiric sales strategies.
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.
Word integrated an entire programming language (WordBasic), with which you could not just create macros, but entire applications complete with dialog boxes. I used WordBasic to add features to Word years before they were offered, such as page numbering that spanned documents.
