Where have you found that statement? The "s" stands for "system",
not for "static". See for example [1].

Traditionally, these programs used to be in /etc (!), and were moved
to /sbin later. For example, documentation of V7 Unix [2] says that
"dangerous maintenance utilities" live in /etc (and doesn't mention
/sbin at all).

Somewhat later, in 4.3BSD NET/2 these system binaries are in /sbin:
"system programs and administration utilities fundamental to both
single-user and multi-user environments" [3].
