An article has been published on the Hyperbola wiki addressing Rust's problems in the context of software freedom, as well as the need for development within the trademark-independent Mozilla Corporation (subsidiary of the Mozilla Foundation, annual revenue of about $0.5 billion).
One of the problems discussed in the article is the fact that, unlike C, Go, Haskell and other programming languages, Rust is a trademark, and not a name of a programming language, allowed for use without the consent of Mozilla Corporation.
