A trademark on the word "Rust" has nothing to do with whether the language itself is proprietary. Clearly and Objectively. What you can call something and whether you can legally make the thing or have a permissive license to an existing implementation are two completely unrelated things. For example, you also can't make a C compiler and name it the "microsoft C compiler" due to your lack of trademark right. Does that mean C is also proprietary?
