It should be noted that from its early days M$ has always been involved with Unix. It even purchased Santa Fe unix, but apparently lacked the programming and/or marketing skills to do anything with it, and sold it. The Win platform has only been increasing its Posix compliance with time.
There is only ONE reason M$ hit it big. The early IBM PC's were loaded with M$-DOS. It became an anchor concept that the PC was equated with M$, just like online auctions are associated with Ebay. The power of advertizing.
As a result Billy G has so much money that he now wants the power to influence world political events with his 'charity'. The only difference between his and the Clinton Foundation is that the latter was used as a money generator. If Gates was really serious about the AIDS problem he would simply buy a drug company and dispense the medications for the few cents a dose it would actually cost to produce.
It should always be remembered that the primary directive of all corporations is to make *profit* for their shareholders, and to increase that amount in every quarter. A shortfall in a quarter would lead to a decrease in share price and financial harm to said shareholders.
While in practice this apples most pointedly to public corporations, legally, it would apply to private corporations as well. Think of the power of venture capitalists *before* the IPO.
Before the Gilded Age of the railroad robber barons the law was simple: Corporations could only receive a charter through a state legislature - and it had to guarantee that it would be acting in the public interest.
Incorporation is an issue entirely dealing with LIABILITY. And it meant shifting the final liability onto the public itself.
The idea of a corporation having legal constitutional rights of a citizen was perpetuated in the 19th century as an act of fraud by a Supreme Court clerk.
So it is a given that all corporations act only in their self interest. Any public benefits are simply side effects. Or advertizing.
And Debian is a corporation. With 'partners':

In fairness though, incorporating was a logical move to keep the developers from getting sued if firmware based on it crashed a passenger jet, or something of that magnitude.
The real problem is the apparent 'mission creep' of other actors like RedHat into its system.
The other day I installed some software into this Devuan system. It had configuration options for both systemd and sysvinit. That is a good thing. Choice. Thats all some of us simply ask for.
