That's probably due to market size. Germany has a market of 80 Million people and the only countries you can easily expand to without a lot of additional overhead are the DACH-region. Compare this to the US and their population of 300 Million people and how influential US culture is in the world and how many people speak English. A US company has a potential market of 300 Million people and use that to support your expansion into smaller markets later. There are probably other factors in play here but it's not surprising to me that Europe didn't produce a Microsoft, Google or an Apple.
