I expect it is a nod to Neil Stephenson's "Snow Crash," which was a book focused on virtual reality that put the Sumerian language in a central role.

Good question. I agree that this is a problem but I wonder whether it is mitigated somewhat by search engine customization. I think the set of people that are simultaneously interested in Sumerian (the product) and Sumerian (all things relating to Sumer, the people of Babylon, etc.) is relatively small I imagine?
