There are several commercially viable desktop OSes other than Windows and MacOS, but they are not mass market. I knowingly wrote my comment to exclude specialist players addressing niche markets because they have completely different adoption dynamics. Actually ChromeOS is arguably mass market. That's all beside the point though really. It doesn't change the fact that the dynamics that drive consolidation are actually in a very large part motivated by user self interest.
