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.
