I mean, sure, you can make great profits when you put morality asides.
Which Gates did again and again.
People forget about this today because of the extensive PR of the last decades to wash the sins of the past, but Gates and MS were basically in the middle of a scandal every 6 months in the 90. Quite amazing since twitter did not exist to report it.

In fact, when IBM came to Microsoft to talk about licensing their programming languages for the PC, it was IBM who wanted a packaged deal i.e. get the OS from Microsoft as well.
And it was Gates who told IBM reps to go talk to Kildall.
Only when Kildall apparently blew them off Gates took a great risk by promising to deliver an OS as well. And he did it by buying an existing product to use as a base and evolving it.
It's all well document from both Microsoft people and IBM people.
And in a few years, there will be no documents stating anything wrong about Gates, only the praises.
