I mean - I agree with a great deal with what you say...but Rust is backed by Mozilla which has written arguably the first or second most popular browser in current use. So, the bigCo argument seems misplaced. Also Google has a history of releasing languages that are often hugely unpopular (cough Dart cough) so I'm not sure that the money argument even holds even if it were true. Cool link though - Rust seems to be very popular among people who know of it, but don't use it.
