Shortly before COVID there was a string of amber alerts arriving in the wee hours of the morning in Ontario regarding missing children. Didn't matter where in the province (larger than many European countries) it happened the alerts would to out regardless. A mix of people complaining about it and social media about why you're a bad person if you don't welcome these alerts. But inevitably they went away by and large. Not aware of any stated policy change I just suspect that they have become more conservative about sending them out because it was frankly ridiculous. Rousing millions of people from bed with any regularity over things they absolutely do nothing about would have only snowballed into a demand that it stop, even with the social media engine shaming people
