It's a little too convenient that the US blew so many weeks of lead time in getting mass testing running. We don't need to suppress information about our virus outbreak when we simply don't have data about it. We literally would've had a better response if the CDC didn't exist at all and individual states weren't impeded from running their own tests. The Seattle Flu Study was explicitly forbidden from testing for coronavirus, and their refusal to obey that order on ethical grounds was probably the reason that they're not suffering New York's fate right now.
Not to absolve China here, but it's a classic sin of nations to hide epidemics (see "Spanish Flu") and they probably aren't even the most egregious sinners today.
