When electronics is on, it is dissipating heat, and therefore the components
are hotter.  When you turn the equipment off, the equipment cools down,
thereby components are subject to thermal contraction.  Same with going from
the off to on state, the components are subject to thermal expansion.  This
does in fact cause critical wear to some components.

There is also the issue of power on spikes, as well as power off spikes.
These can be mitigated to a large degree, but that depends on the design.
