Tom like to make an argument out of everything, including symantics.
Most reasonable folks would agree that if a protective device shunts a
surge to ground, that it has in fact stopped the transient, because the
destructive transient does not make it to the protected equipment.

Granted it is a minor point. But the point is made because many
assume a plug-in protectors sitting between a transistor and a surge
will somehow stop or block what three miles of sky could not.
Effective protectors 'shunt'. Those protectors that don't have earth
ground hope one assumes it will instead 'stop' or 'absorb' a surge to
promote a myth. Even shunt mode plug-in protectors only shunt - divert
- a transient. To be effective, it must shunt to earth and not divert
into the appliance. A 'semantic' that can otherwise create confusion
- promote an ineffective product.
