Not everything revolves around software.

Also even then OSS generally seems to only be universally successful in areas where software is a "cost centre" i.e. companies are willing to invest into it when it makes it cheaper for them run their business than building/buying proprietary stuff or they build their products on top of it (A but almost never when it's the actual end product targeted at consumers.

And if we extend the definition of software to video games, OS is not even a thing there (besides middleware of course which falls into the previous category).
