That seems like a very reasonable requirement. How can you expect to participate in society, especially elections, without a decent command of the local language?
By hiring a local accountant and paying a small fortune in taxes? If I learn the language then yeah cool maybe I'll get into their politics thing but it's not that if I don't vote I'm not going to be a productive citizen. A lot of countries let you become a citizen without learning their language, most notably the US.
Being a part of society is a lot more than working and paying your taxes.

An English test is required to become a naturalized US citizen. https://www.uscis.gov/citizenship/learn-about-citizenship/th...
On the other hand Italy denied my application once already, after my great grandparents basically left the country because Italy was not defending their town from Germany. They rejected my application because they say my great grandparents were not Italian but Austro-Hungarians. The lady at the consulate was super racist to my grandmother about it, in my face. After that now there's another way I could get my Italian citizenship by birthright by suing the government because of another racist thing they use to do where women were not transferring citizenship.
Again the US is not great but a lot of this things make me feel whatever "racial tensions" I may be a victim of in the US are mostly the media blowing stuff out of proportion, when most of the "racial tensions" I felt dealing with the EU are actual racial violence or discrimination that either me or my family where victims of.
