I think a missing part of the story here is what happened to WordPerfect after it was sold off to Corel. Corel realized that Microsoft would be one hell of a competitor with Office, and (correctly) feared that Microsoft would abuse their Windows monopoly to push it.
Corel responded incredibly boldly, by rolling their own Linux distribution and bundling Wine, which in turn was sponsored by Corel. Unfortunately, they were a bit too ahead of the technology with this move, as neither Wine nor Linux were quite ready enough to usefully run desktop applications other than WordPerfect.
