Let us not confuse git and Github, the later belonging to a reviled US monopoly.
I used to revile (can you use this verb this way?) M$ in the 1980s/1990s as well, but at the moment I could think of several tech companies that I like even less. And yes, technically they can still be considered a monopolist because of Windows, but it has lost a lot of its significance...
The monopoly is live and well with Office, which is their real money maker.
I thought it was Azure now.
Azure is the biggest revenue source, but my guess is (didn't find data) that Office is more profitable.
Although Microsoft is especially good/evil at getting Azure lock-ins and overpriced exclusive deals from e.g. governments.
Windows 11 hardware requirements alone top most things the other corps have done over the last decade.
Indeed,
Github is high quality, software engineering enablement platform
And git is letter management engine
