This bundling successfully knocked out the leading word processor (WordPerfect) ... from the market

Nonsense -- what blew WordPerfect from the market was the appalling version of WordPerfect for Windows they relesed around 1992 that was so bug-ridden it was unuseable; I had to use it for a 2 day course in 1992 where it crashed literally every 5 minutes, even when you weren't doing anything complicated.
