As far as I know for Microsoft, a large chunk of their revenue comes from the licensing for Visual Studio, the Azure service and the fees required for certification, and surprisingly the Xbox division. Corporate entities buying licenses for Visual Studio would likely be tens of thousands of dollars each since the Enterprise level license starts a little under two grand. And Xbox with it's recent push into mobile style games likely makes Microsoft unimaginable amounts of money. Roblox in 2021 is estimated to have made $1.9b based on it's microtransaction model, and Microsoft gets a cut of that. The FIFA games generate an average of $1.5b every year. With the recent acquisition of Activision-Blizzard and thus mobile giants like King Games, it's likely that Microsoft could rake in $30b a year from the Xbox division, an increase of seven or eight billion. And with the autonomy model of the owner, publisher, developer ladder Microsoft likely has to do little to no investment as the parent company in order to receive that income.
