Yes but that's my point. Monopolies don't last. We have other ones now yes. But that's because the earlier ones died.

And yes we still have windows as the major desktop OS but don't forget, in the 90s/early 2000s windows was equivalent to computing.

These days the desktop OS is much less relevant than it was and many people don't even own a laptop or desktop anymore. They just do everything on their phone. And Microsoft totally and completely lost that race.
