I’m not sure I agree. Windows still has 95% market share in Steam’s hardware report. And even the modest gains that Linux has seen in this space have been as much a result of the efforts of a few small companies who have financial interests in undermining Microsoft’s monopoly as it has been a display of grassroots enthusiasm for open ecosystems.
Entrenched technologies take a while to un-trench; there's a lead lag on that kind of thing.
It starts with the kids saying I hate Windows. Then the adults. Then finally the grandmas. Windows will be evaporating marketshare for decades, like a long-half life on an unstable isotope.
