But unlike Google (AFAIK), Microsoft played very dirty - they eventually paid for it (see e.g. [0]), but the gains from remaining a not-even-threatened monopoly where at 100-1000 times larger than what they paid.
I experienced this first hand at a company I worked for in the early '90s - we had agreements signed with many PC manufacturers to include our software (which was a DOS launcher of sort, that -- in those days of Win3.0 barely coming out, was more favored by users than Win3), and then all of a sudden, within 3 weeks, every single one of the manufacturers canceled -- and it later turned out Microsoft just visited each and every PC manufacturer and told them their MSDOS "discount" is going away if they bundle our launcher or anything similar.
In other markets, e.g. Office. in which, at the time, they were not a dominant player (Lotus123 was king, Borland Quattro was a strong player, Excel was less so; WordPerfect was king of pword processing), they actually competed by turning out better products.
