The biggest problem here, though, is that look at Google in web standards: the web is now what Google say it is, IE 6 style. If Googlers don't get their way with the Rust language team, they'll just attack the language team head-on, or bypass them. Google have zero interest in collaboration.
Google employees have actively gotten involved in collaborating within the Rust project rather than bypassing it. Of course, anything can change at any time, but this absolutist statement doesn't correlate with experiences so far.
(Also, these organizations are huge! The web standards folks and the Fuchsia folks are, as far as I know, basically disjoint, so even talking about companies like Google as a monolithic entity is fraught with issues.)

We work directly with Google folks. This has not been our experience in any way. Likewise for other large companies interested in specific Rust features or improvements.
