An article has been published on the Hyperbola project wiki that discusses the issues of the Rust language in the context of software freedom, as well as the need for development independent of the policies of the Mozilla Corporation trademark (a subsidiary of the Mozilla Foundation, with an annual revenue of around 0.5 billion dollars).
One of the issues discussed in the article is the fact that, unlike C, Go, Haskell, and other programming languages, Rust is a trademark rather than the name of a programming language permitted for use without the consent of the Mozilla Corporation.
