Rust didn’t start out community-driven either - it was a single Mozilla researcher’s “pet” project. It’s important to keep in mind that when the languages you listed started out, it was hard to impossible to have a community; internet wasnt as ubiquitous as today, let alone enablers like Github. If they were then perhaps those languages would’ve evolved differently as well, possibly for the better.
I also don’t think Rust is as community driven as you make it sound. There is a core team, that while open to outside opinions and contributions, ultimately decides on changes and steers the ship.
