Yep, but you're techsplaining to someone who already know this. But still, it's not opt-in. It's always on by default and litters stuff without asking. All that does is create a file but that doesn't remove the traces of all the tracking it leaves behind without asking. This fixes it in a oneliner:

    # mac, bsd, linux, and wsl only
    (d="${XDG_CONFIG_HOME:-$HOME/.config}/go/telemetry";rm -rf "$d";mkdir -p "$d"&&echo off>"$d/mode")

Like television and telephone, the "tele" (remote) part is the crucial and defining one. Without it, it's just metry.
