Given the fact that the US has an overwhelming dominance in software development (including for the cloud) I think that the claim this is only a US phenomenon is somewhat moot. As a simple counter-point, the choice of development workstation in the UK seems to mirror my previous experience in the US (i.e. Macs at 50% or more.)
My experience in Germany and Austria mirrors GPs experience with windows/linux laptops being the majority and Mac being present in well funded hip startups.
