The more I think of who I wish would buy them out based on some of the things they've done for side funding. I think someone like CloudFlare (not Google, Microsoft or Apple) would fit the bill for me. Mozilla birthed Rust, they very likely still have Rust talent onboard. CloudFlare relies on Rust for critical software.

I kind of miss the world the Mozilla was going all in on Rust for Firefox, I think the language could benefit greatly from it, especially in terms of out of the box libraries. One of my hopes was that Rust would eventually build out a standard GUI stack that's cross-platform that would be used by Firefox, but could be used by everyone. Same could be said of all the different pieces that make up Firefox, including the JS engine, could have been its own discrete Rust crate.
