The power to send mass messages to a whole country is the worst thing google/apple have given to governments across the world.

This implies that governments didn’t already have this ability, which appears to be largely untrue? To my understanding, many countries already had emergency messaging systems, and mobile integrations are just a way of modernizing them.

(It seems exceedingly good that the government can warn every civilian about natural disasters, etc.)

These aren't from Google or Apple, they're from the wireless providers: https://en.wikipedia.org/wiki/Cell_Broadcast

This is not related to Google or Apple. And this extreme alert, it's sent even to cable TV automatically. In a few countries, it's sent even on Fax lines.

If you say so. In the meantime I’ll continue to appreciate the occasional tornado warning.
