Re: There are 2 things to take into account
I suspect that the British app they're referring to is the Covid-19 Symptom Tracker, produced by health science company ZOE to support research led by Professor Tim Spector at King's College London. It was instrumental in tracking the early spread of the pandemic in the UK (I don't know about its USA usage) and lead to the identification of several unusual symptoms as well as the emergence of 'Long Covid'.
OTOH, the company behind Coronavirus Reporter sounds extremely shady. Apple might indeed be capricious in the way they enforce their App Store rules, but I don't think this was a bad call.
