Your comparison is more apt than the GP's, but I don't think political municipalities are apt analogs (or at least they don't capture all of the nuance at play here). What we have is heterogeneous people groups (not a single identity) who live in a particular non-political geographic region wanting another culture's name for that region. I guess it would be as though the people of the Alps decided that they should own the .alpine TLD, but that doesn't completely capture the multilingual concern you were discussing...
