Which is why your telco stops all phone service when thunderstorms
approach? Which is why all radio and TV stations disconnect from
their antenna and power lines to protector equipment?

Routine is to have direct lightning strike with no damage. But that
means installing solutions that costs less than the Belkin solution.
That means installed what was even well proven 100 years ago. That
means learning well proven technology that many today would rather
mock than learn.

Surge that need not enter a building to find earth ground does not
cause electronics (or light bulb) damage. Therefore your telco also
never has computer damage and need not disconnect during storms.
