I think Marvin_0 has made some excellent points, which unfortunately you seem to have ignored and instead just concentrated only on the size issue.
Size does matter when it comes to languages, however, that's not the point here. The point is that English is (by far) not spoken by everyone in the German world and the LOTUS-Community.
Another point he made is that Germans like Simulation-games. And I'm sorry to work with clichés here but many of the 7 billion people on earth have other things to worry about than playing LOTUS. Also, most of the content for LOTUS currently available is German (which is why there's fewer players from abroad, which is why there's less content from abroad, and so on).
But sure, continue to ignore the facts and keep wondering (or it seems you just dont care) why again most of your community is from German speaking countries by justifying that it's only German speaking people who mostly love simulations.
Nobody is ignoring the issue at hand, however, people are explaining it. This is a key part in resolving the issue of internationalising LOTUS.
Being offended by people explaining stuff and claiming "discrimination" will, however, not help.
