Honestly.. That pisses me off. I couldn't care less if it only affected you, but, if you are affected, emergency service will be forced to waste resources on you.. Instead of using those resources on genuine cases that need it...
It's literally just a priority alert. The AFP aren't taking control of your phone, and there is no evidence you're going to be flooded with alerts either.
Like at Mt feathertop in winter, I've had f**kwits in my hiking group REFUSE to listen, when I say "don't go to the peak, you don't have a ice axe", and their response is always the same "if I slip, I'll take responsibility". Yeah, Alpine SAR will STILL have to fly you out, and if you get injured, their family will STILL blame me. And those resources are completely avoidable
Or VMTC who is encouraging people to "go out and just enjoy yourself and learn what you can withstand" (and I've seen them say this to new hikers who have barely tested their gear), and refuse to ever cancel trips, even with catastrophic conditions forecast.
If the idea of a priority alert is so scary, then so should phone calls, and messages, because the only difference here is that its a area message which ignores silent mode.
If it's abused, sure, makes sense to turn it off. There's no evidence of that
