So far I've only followed Rust peripherally, but if Amazon is going to drive it, that makes me more interested in adopting it. Experience with Scala, and contrast with Golang and TypeScript, makes me want to use a language that has a strong corporate backer.
As far as I understand it, I think the desire here is for diversity in backers; Steve (and Mozilla) wasn't comfortable with Mozilla being the strongest influence, and he just wants to make it clear he disagrees with Amazon replacing Mozilla in that respect. It sounds like he is totally appreciative of the support Rust's ecosystem has received already and will continue to receive.
