I never understood this sentiment. Even if nobody on my team uses Emacs or Vim, or Clojure, Rust, Zig or Nix, or some browser extensions, or any other tool, nobody could ever directly deny me access or restrict the use of any of that on my machine, some vm-box or EC2. And once I prove their usability to me personally, I show that to my colleagues and typically people when impressed they start using them. Once you have more than three people, you can start discussing rolling it out for general use. Just this past year alone, I have convinced my teammates to use a bunch of tools they'd never heard of before.
