My understanding is that sbin for system binaries, not necessarily statically linked. Normally /sbin is only in root's PATH, not normal user's. They are likely world executable, but in many cases you cannot actually run them as non-root since they usually touch things only root can access without special access (e.g. raw devices, privileged syscalls, /etc/shadow etc.). Not always though, like you can run /sbin/ifconfig as normal user in read-only mode.

The s in sbin stood for static initially. Of course nowadays this is not enforced.

What is the source for that? Some of the oldest references to sbin I can find are 4.3BSD Net/2 man pages (https://man.freebsd.org/cgi/man.cgi?query=hier&apropos=0&sek...) and Filesystem Standard v1.0 (https://www.ibiblio.org/pub/Linux/docs/fsstnd/old/fsstnd-1.0...). Former doesn't mention anything about static binaries, latter only mentions that static ln (and even mentions sln being static version of ln) and sync can be useful.
