Continuing on your analogy, I would argue we have less diversity due to the all-encompassing three major OSes.
Similarly to how you don’t really get competitors to eucaryotes and prokaryotes, the initial investment (device drivers) to create an OS (organism) that is actually usable is so high that one basically can’t overcome it when others are available.
