What I wonder, and I do not mean this in negative way, is whether this would have happened in a more commercially oriented organisation. Mozilla remains a foundation, and I consider Rust a fruit of their labour in itself.
To put it another way, I find it hard to justify developing Rust just for a web browser. But if you consider it from the perspective of a foundation developing tools for the developer community as a whole, it makes much more sense.
