I don't know but perhaps recent social unrest could have something to do with that?
Europe is getting tired right now, and I'm not talking about economies but about people. You can't lock people for months and expect them to to obey indefinitely. It's unsustainable. It's more reasonable to apply some proportional restrictions than to lock everything down. Eg. limit users of a gym and require disinfection. That's how a legal state should work: effective and proportional restrictions, rest is a human right.
NYC saw substantial social unrest and didn't see any COVID spikes; marches and demonstrations have extended for months and the test positivity rate remains low.
I believe it's the decision not to reopen indoor dining and bars, and to mandate masks, that saved NYC the resurgence that the rest of the country has seen. You absolutely can control COVID even during the current period of social unrest; the US largely chose not to. COVID doesn't seem to like to spread that much during largely masked, outdoor protests. It loves to spread in bars and parties.
School is opening soon, so things will probably get worse, but nevertheless: NYC demonstrates that in an American context, COVID can still be controlled pretty well.
(NYC government has a lot to answer for w/r/t the initial response in March, but that's not the same issue)
