I agree. I've recently become interested in the Gemini protocol, but between the space programme, the crypto exchange and various other uses of the word it's difficult to find related content without some extra Google-fu. It's exacerbated by the fact that most software written for the protocol tends to stick with the space theme.

I'm not sure if there's a term for it but it's like linguistic debris. The namespace is being polluted; eventually it won't be obvious what any particular word refers to.
