A genuine question - is it felt by most that this is an intrusion? The little that I’ve heard from British news is that it’s a demonstration of how a public warning via mobile phones will be used if something really bad is happening and/or which is a threat to life ? But that this one occasion is just to illustrate what happens, so that everyone with such phones has a better chance to avoid a major event in future, weather event, terrorist attack, etc., Hope I’ve got that right.
I do object to a lot! But I can’t see the reason for objecting to this. Our own (lower tech) local warning system here in France involves sirens wailing as a test for about 3 minutes on the first Wednesday of every month at noon. Hear that any other time and we’re in trouble. Nobody minds, people are reassured by the existence of such systems. I can certainly think of bigger reasons to be annoyed just by the daily bombardment of junk and nuisance calls on my ‘phone.
