I sit next to a guy in Mountain View that works full time just on teaching people Rust and integrating Rust into Android. There’s a whole team dedicated to getting Android developers writing Rust.

The difference in installation procedure is probably a security measure. Piping curl to bash is a bad move and it’s the Android security department that’s pushing Rust in Android. Plus, internally, Google has well maintained aptitude repositories with projects built from HEAD. It’s nice installing something like lldb from the command line and the internal Python interpreter is the latest version. And you know all of your coworkers are running that version, too.
