I instinctively distrust any company that makes their national origin the main selling point. To me that's a subtle signal that they cannot compete on technical merit.
I mean, yes, but some governments may be tied to using European alternatives by regulations and some individuals may prefer not relying on US / China models for various reasons (could be political / personal preferences).
This is a universal problem, interesting enough especially you'll notice that in the automotive sectors a lot. Crappy local automakers pull the nationality card because they can't compete on real engineering.
