On the one hand, all the attention (if pride is removed from the equation) should be win-win since remote workers might end up less spied on or hacked and zoom still makes a huge profit.
But in answer to "why is HN shitting all over Zoom", I think the answer is "because they aren't doing good enough".
There's no malice there (on the posters' side). If Zoom does better people won't have cause for shining a flashlight on their data privacy policies or security holes. We will see if Zoom grows up fast, since the momentum towards them is already so large I don't see it changing prior to the Fall when schools might risk re-evaluating their tools.
