This is excellent, frankly almost unbelievably good news. On the one hand, I'm still bummed at Mozilla's recent decisions re: layoffs. But with these 3 companies picking up the torch and increasing their investments, that is a ringing endorsement of Rust's viability for greenfield projects (and that compiler checks > coders conventions in improving software memory safety)

Having maybe kicked off a small flamewar with my above comment, I will admit to being curious to contribute to deferring the eternal september of rusts community and how welcoming it is with all the influx of new developers, myself incuded in em.

Theres probably a netiquette equivalent somewhere, but beyond "don't act like the rust evangelism strike force" of n-gate fame, I'm fuzzy as to its details.
