There's more to it, too.

Static linking is not only a risk with regard to security vulnerabilites.

You cannot retest against an updated static lib without relinking the
dependencies. You don't learn about new runtime breakage (or regressions)
caused by the changed static lib, because the programs still use an old
lib linked into them. The changed lib may have been out for many weeks as
an update, but nothing test-drives it. What a surprise, if the lib were
found to cause a sudden problem for a minor rebuild of a program. Or
worse, if the rebuild were released quickly because of expecting it to
be harmless, but the static lib under the hood has changed and breaks
runtime for users.
