You're mixing up market with home team. Of course an EU company will focus on marketing, service and deployment most heavily in EU as it's the market it knows best, and as a result, will have a stronger presence. So it's a push, not a pull. The only cases where this is not true is for companies that are grossly export oriented - and these are usually located in smaller (for the given product class) markets targeting big ones like EU/US/Japan -> see China, Korea, Taiwan, etc.
