Ok this is bullshit, if you think all the anger against them boils down to downplaying the virus, then you don't understand what is going on. They have been accused of holding info from the public about the virus, letting China lie about it, being their puppet. Trump relied on this info originally but closed down before the Dems wanted it, Pelosi even said go to China town it's fine (not exact quote) early on in this. If the economy crashes you could make the claim about it's Trump fault, but the death toll is not. Not to mention they actively avoid questions about Taiwan's situation in all of this as if Winnie the Pooh is right behind their back. This isn't just Trump. Japan's not happy either. And I'm sure more will consider soon.

But they did not downplay it:

Now is the WHO a saint no, but is kind of hypocritical to basically blame them for things he has done himself:

From downplaying it, to announced is cured, to claim it is a democratic hoax, etc. and yes he even said China did a good job at containing it, basically everything he is blaming others he has done himself
