I think you miss the most important bits:

- backdoor deals to discourage alternatives, such as moving headquarters to convince people not to use alternatives,

- monopoly abuse,

- active sabotage of alternative software by intentionally triggering false errors if used with competitors' software (DR DOS),

- unleashing Internet Explorer on humanity (which proves that AI can't be that bad if humanity survived that)

You know, the stuff that every philantrope like Gates does all the time.
