Operating systems seems like a weird one to throw in there. For a start I'm pretty sure some Finnish guy wrote and maintains one of the better-known operating system kernels, which happens to be used in certain popular operating systems as Ubuntu (UK) and SuSE (Germany).

Or perhaps you meant mobile operating systems, in which case I would note that the most promising and well-known mobile OS after Android, iOS, and Windows phone (all American) is SailfishOS, which is... Finnish.

So the US is definitely on top, what with all the software tech giants being based there, but Europe seems pretty relevant.

I was thinking more alongside of mobile systems, true, but I never heard of SailfishOS. I think it's pretty irrelevant in the market right now.

Also FOSS software can't solely be attributed to the one guy who started it. I would say the Linux Kernel is global and it took a lot from Unix.
