Earlier quoted context omitted.
What emergency alerts would BigCo push to people on its campus? There would be no consent btw, they'd just fire anyone who didn't enable the alerts.
Active shooter, chemical spill, any kind of building emergency like water stoppages. And then if it wasn’t tightly controlled and carefully managed, probably things like social events with free snacks, company all hands announcements, and single cars blocking someone into a parking spot. I see the usefulness of more fine-grained subscription, but also see the abuse potential from giving more people access.
If the end user has full control over subscriptions then spam will simply result in silencing or unsubscribing. As opposed to right now where it's all or nothing and it isn't even authenticated. So for example either I get spammed with amber alerts from 100 miles away or I opt out of wildfire warnings. Not a great trade off.
