Huh? Go has its tradeoffs, some people don't like it and that's fine. But nobody can deny that it is by far one of the most 'readable and reviewable' (the argument in question) mainstream languages.
If Googlers think that Rust code is just as readable as Go, even though Rust obviously makes tradeoffs against readability for other features, I would be tempted to mark that as Googlers just having a culture about being overeager to think the tools they are using are the best.
