I'm not aware of any low-level devtools having any kind of telemetry. Rustup, cargo and rustc don't have any telemetry. Rustup used to have some ages ago, but it was removed. Similarly, NodeJS/NPM, LLVM (clang, lldb), GNU (gcc, ld, gdb, glibc), Java (OpenJDK), etc... none of them have any telemetry as far as I know. If they do have some, google isn't being helpful at finding out about it.
