One of the biggest difference between the NHSX approach and Apple/Google is that Apple/Google will send an alert from anyone who reports symptoms even if those are malicious or misreported. With the NHSX approach a test will be sent out, if it isn’t completed or comes back negative, that reporting will be discounted creating less false positives.
I know for my own experience the more notifications I get from a service, the more I am likely to ignore and miss the important ones.
