There are some situations where you would use the definite article for singular proper nouns, such as with some geographical names, or when the name is actually a combination of common and proper nouns.
I would also use the definite article if I were referring to a specific language's Wikipedia - "the English Wikipedia", "the Swahili Wikipedia", et al. - instead of to the Wikipedia project in general.
As for referring to Wikimedia, in English one would say "the Wikimedia Foundation" since "Wikimedia" clarifies which foundation we're talking about. If the name didn't use the word "foundation" - if it were "Wikimedia Earth" or "Wikimedia United" - then the definite article would not be necessary.
