The decision to partially "let go" of Rustlang as an asset on some level makes Mozilla something like the anti-Google. If Mozilla make this a habit, they'll come closer to achieving their mission, and the spirit of FOSS. It's a worthy goal, using your power to spin off great pieces of software into independent organizations. I mean, even old "Micro$oft" now knows that open source is more of an asset to them than a competitor. Good to be coding in a time like this. :)
