No, it has nothing to do with that. It's policy driven. The Dutch realized they can get in on what the UK was getting if they swallowed their pride and started speaking more English and allowing English as a language of business.

Germans are too proud and expect the world to start speaking German instead.

I lived in both countries, Germans have equally good English, but you would struggle to use English in official capacity in Germany. Whereas in the Netherlands they are very accommodating, and not because they are kinder. They do this on purpose, cause they know they can (and did in fact) attract a lot of foreign money that way.
