That may be the case in your line of work but not in
mine. A "Simple Harmonic Oscillator" is one in which
the restoring force is linearly related to the
displacement and that relation is what is being
described as "linear".

The voltage is what tries to restore the quiescent
conditions and is linearly related to the current
hence in normal terminology it is linear.

I know that only too well :-(

Sorry Aleksandr, I am not taking any more exams this
week, I think I have established my credentials
adequately.
