[Six Nifty .50s]

I sense a stalemate here. I would say that both Ruy and Jukka have a case.

In a free market system any potential customer, like Jukka, has a right to make demands for specific products. If a potential supplier wants his money, they will try to provide what is demanded at a fair price. But the supplier does not have an obligation to do that, and may not have the funds or time necessary to translate research into foreign languages.

Obviously you cannot always trust the accuracy of translation, and the most practical way to avoid that problem is to learn the language used in the original texts and documents.
